Kimchi

I just broke into my latest fermentation experiment, a fantastic kimchi with lots of goodies, including arame seaweed. Kimchi is a fermented cabbage condiment that originates in Korea but is similar to sauerkraut. The main difference is seasoning - kimchi most traditionally is seasoned with ground red pepper, onion, garlic and ginger in addition to the salt. It can include any number of additions or substitutions including cucumber, carrots, different types of onions, root vegetables like radishes, fruits like apples or raisins or even stranger things like shrimp paste or raw shellfish. Koreans have hundreds of variations and these photos by eryoni taken in South Korea show just some of the diversity of Korean pickled vegetables.

This batch I made included the exotic addition of arame, a type of seaweed. Seaweed is a great thing to add to anyone's diet for the trace minerals and rare proteins and sugars. Arame, the common name for the kelp Eisenia bicyclis, is a rich source of calcium, zinc and iodine. It is also a good source of lignans which help fight cancer according to some studies. As expected, its taste is hardly noticeable in the highly flavored kimchi, though it is visually apparent as black threads in the cabbage mix.

Note on amounts: I don't give any. That's not the important part. To make one quart of kimchi I filled up a 3 or 4 quart mixing bowl with shredded veggies and seasonings. I would expect this is about 3/4 of a medium head of cabbage, 2 good sized carrots, 10 big green onions, a handful of arame, 3 inches of ginger, 5 cloves of garlic and enough chiles to make it red and spicy. Enough salt to make it "too salty to be tasty, not salty enough to be gross". See my blog posts on making sauerkraut, making pickles and my pickle FAQ for more information on my methods.

I used a mix of ground whole dried peppers and commercial New Mexico chile powder. In the past I have used a mix of chile flakes (like for pizza), cayenne, New Mexico Chile powder and paprika. You should use however much of whatever you have. This is artisanal cooking!

Shred the cabbage to your liking and either chop, plank or ribbon the carrots with a vegetable peeler. Chop up the green onions however you see fit and mince the ginger and garlic into matchsticks or tiny specks, as you see fit.

Put the handful of dried arame into a bowl of warm water and let sit for 5 or 10 minutes.

Toss all of the veggies together with the ground chiles and salt in a large mixing bowl or cooking pot, tasting as you mix. Pull the arame out of the water, squeezing it as dry as you can and leaving all the grit behind in the bowl. Mix that into the veggies and continue mixing, tasting and adding salt or chile powder as necessary.When the veggies and seasonings are mixed together well and good and salty you can either leave it in the bowl for an hour or so, or start packing it right away. I have gotten lazy and been leaving it in the bowl for a while to allow more liquid to come out of the veggies and make packing it easier.

When you are ready start spooning the mixture into your clean quart sized jar. Really pack it down in there. I use a regular mouth half pint jar to push it down into a wide mouth quart jar, but I've also used wooden meat mallets and those Chinese soup spoons to pack the veggies down. You really want to squeeze all the air out of the jar and let the liquid come up over the veggies. If you are squeezing and squeezing and still not getting liquid over, or at least to the top of your veggies you can add some more brine - salt added to water until it is too salty to be tasty but not so salty it makes you gag. You will end up with a wetter kimchi, but it will ferment just the same.

Put the lid on your well packed veggies and leave them on the counter for a couple days. I find that ferments with ginger in them seem to get fermenting much more quickly. I did this kimchi a day after doing a plain cabbage kraut but the kimchi was ready to go in the fridge a day earlier. It was fizzy and the lid was popping and it was smelling quite sour. Put it in the fridge and start eating it whenever you want something spicy gingery sour salty.

I have been eating this kimchi with everything. My favorite is kimchi and macaroni and cheese, but I was also really impressed with kimchi and colcannon - mashed potatoes with sauteed cabbage and collard greens. It's of course great with any stir fried vegetables or Asian flavored meats, and I tossed a fair amount into a bowl of instant rice noodle soup the other night. I think the trick to incorporating fermented vegetables into your diet is just putting a spoonful on your plate with every meal. No matter what the food you are eating is, try it with some sauerkraut, pickles or kimchi. Maybe you won't like it and you don't eat that spoonful. Then again, maybe you will love it and have discovered a whole new taste sensation. And isn't that what life is all about?

Of Probiotics and Pickles

If you are in anyway connected to the world you've probably heard more and more about probiotics and beneficial bacteria. People are selling probiotics as pills, liquids, juices, yogurts and other fanciful items. Most of you have probably seen the yogurt commercial with the slightly disturbing animation of an arrow on a woman's stomach and you might even be able to hum the jingle for that product. What's all the big deal about probiotics anyway? And do we really need to spend top dollar to have them added to our foods?

The term probiotics refers to bacteria and yeast found in food that are good for your body. Our skin and intestinal tract are completely covered in bacteria and the idea is that inviting the right kind of bacteria into that system has health benefits. The human gut can contain over 2 lbs of intestinal microflora (beneficial bacteria) and they do some pretty important work there. They help digest food and create vitamins, they make it hard for bad bacteria to live there and stimulate the part of our immune system that is in our digestive system. In fact, there is more and more evidence that everything from acute intestinal upset to allergies to autism can be helped by normalizing gut bacteria and using probiotics. There are lots of good commercial probiotic foods and supplements available (as well as some not so good ones) but being the DIY kinda girl I am, I like to make my own.

Yogurt, kefir and buttermilk are all very common probiotic foods. These are all fermented dairy products that are eaten while the bacteria are still alive. Vegetables and fruit can also be cultured into probiotic foods through a process called lacto fermentation. A couple months ago I wrote a tutorial for making sauerkraut, one of my favorite kinds of lacto fermented vegetable. Sauerkraut is a great way to start in on fermented vegetables because most Americans at least know what sauerkraut is and many even already like it. I've been surprised at how many of my friends are excited to try my sauerkraut because they grew up eating sauerkraut. Sauerkraut is not the only pickled vegetable out there so don't despair if you don't like the kraut.

Vegetable pickles are possibly even easier than sauerkraut and allow for as many variations as your imagination can come up with. The basic idea is to cover vegetables with a salty brine and allow the bacteria to do their thing. I'll give you a recipe-tutorial for my very favorite pickled vegetable recipe and list some of my favorite variations here and then I'll answer some common questions in a follow up post.

Spicy Carrot Pickles

I like Spicy Carrot Pickles so much because they come out great every time. They are salty, spicy and a bit sour and always have a great texture. You can adjust the amount of spiciness to your liking using different kinds of peppers. These are based on the pickled carrots usually served at autentico taco places so they should be sort of familiar to a number of people.

Step One: Jar and Vegetable Prep

Find a glass jar with a tight fitting lid. A pint sized mason jars with a metal or plastic lid is great but an old pickle jar work just as well. Wash the jar and lid with hot soapy water and rinse well.

For a pint (two cup) jar you will probably use 1 1/2 - 2 medium carrots, 1/2 an onion, 2 cloves of garlic and half of a jalapeno. Have more carrots available in case I am underestimating and adjust the garlic and pepper as your family would like. I find half a jalapeno adds heat but is not blinding, but you may have widely different tastes. You can use a hotter pepper like Serrano or Habanero (if you dare) or a milder pepper like an Anaheim, a Hungarian pepper or a pizza pepper. Be sure to adjust the "half a pepper" accordingly to the size and heat of the pepper you choose. You could also use a pinch of red pepper flakes instead of fresh peppers.

Wash the carrots but don't peel them. Slice them into long ovals by slicing on a steep diagonal to about 1/4 inch thickness. Peel and slice the garlic cloves and slice the onion longitudinally (from pole to pole, not around the equator) into 1/2 inch slices or into chunks. Slice the jalapeno into rings. Layer the vegetables in the jar to within an inch of the threads.

Step Two: The Brine

There are all kinds of recipes out there for brine strength ranging from a specific measurement in the jar to percent salinity. After reading The Ultimate Kimchi recipe and Wild Fermentation by Sandor Katz, I decided to do this the old fashioned way - use my taste buds.

I make a brine by adding salt to water until it is "too salty to be tasty, but not salty enough to make me gag." I understand that this is a very vague description of how much salt to use, but it works. I promise. Start with a teaspoon in a pint (two cups) of water and taste it. You can hardly taste the salt, right? Add another teaspoon and taste again. Then increase by half teaspoons until the water is really gross. Add a splash of water and taste again. Somewhere in between tasty and gross is the right amount of salt. It always seems a little saltier than seawater to me.

Oh - and use the right kind of salt. You should use sea salt because it is pure and has lots of trace minerals that are really good for you. I personally use RealSalt because it lists the trace minerals on the package and sells for a reasonable price. Other sea salts would be fine too. You can also use kosher salt or other salt as long as it has no iodine and no anti-caking ingredients. One caution about Celtic or grey salt - moist salt is sometimes known for carrying bacteria and mold that can ruin your ferments. If you want to use moist Celtic sea salt then you should bake it first until it is dry. Seriously, though, who needs to go through that much work for pickles. Just buy some lower quality sea salt for fermenting and keep the Celtic for sprinkling on your potatoes.

Once you have your brine made with the right kind of salt to the right saltiness then pour it over the jar full of vegetables. The brine should cover the vegetables but still be below the threads of the jar. Screw the lid on tight and set it on the counter to begin fermenting.

Step Three: Fermentation

Just like in the Kraut 101 tutorial I recommend you check your pickles every day and learn to look for signs of fermentation. The day after you make your carrot pickles open the jar and listen for popping, fizzing or hissing as you open the jar. Smell the contents and then taste a sip of the brine (you can take some out with a spoon or just sip it out of the jar like I do... but then again I'm pretty cavalier about things like that). Is it at all sour or fizzy or still just salty? Put the lid back on and let it sit out for another day.

It usually takes 2-5 days for signs of fermentation to really show up. Exactly how long depends on everything from the quality of your vegetables and the ambient temperature to whether you sacrificed to the proper deities. I'll address some of these variables in the next post and in the end it doesn't really matter how long it takes, just that it happens. Be patient, it will.

When your pickles are popping, fizzing or starting to taste sour then move them to the fridge. Carrot pickles usually taste best after another two or three days in the fridge (you should try them every day to see when you like them best) but will last for months without getting mushy or gross. The onion will start to get a little mushy after a month or so but whole garlic cloves are still virtually raw until at least a month in the brine.

I like to eat these pickles in anything even remotely Mexican in flavor. I love them in quesadillas and burritos as well as on salads. The pickle brine can really brighten up a soup and makes a fine salad dressing when substituted for vinegar in any recipe.

* * * * * * * * * * * * * *

Once you've run through this recipe once then you are ready to start thinking about pickling other vegetables. Here are some of my favorites.

Cucumbers: pickled cucumbers are a classic. I have used whole pickling cucumbers as well as sliced eating cucumbers (remove part of the skin, it is tough and bitter). Pack the jar with cucumbers, dill seed, garlic cloves, black peppercorns and maybe some sliced onion and/or mustard seed. Cover with brine and follow the steps above.

I didn't use cucumbers as my master recipe because I've had mixed luck with fermenting them. Cucumbers, being so watery, are at risk of getting mushy and even when they aren't mushy they never taste quite the same as vinegar pickles do. I like the fermented flavor but have not yet perfected the crunchy cucumber pickle. Some people add a grape leaf to the jar and others soak the cucumbers in salty water first. I'm going to experiment this summer and I'll let you know.

Turnips, Radishes, Not Spicy Carrots: Slice them into planks or chunks and cover with brine. Try these will dill seed and garlic or with mustard seed and red pepper flakes. Turnips tend to be a bit spicy when fermented, but are great on salads.

Beets: I recently made up a jar of sliced raw beets and carrots with no extra seasoning at all. The liquid is thick, sweet and deep red and the vegetables are now tender, sour, sweet. Fantastic.

Green Beans or Asparagus: Trim the veggies to fit in the jar and add a garlic clove and maybe one of those small, dried red chiles. Try doing the same with okra. A little juice from one of these jars is the secret to my Bloody Mary. Fantastic!

Mushrooms: White or baby 'bella mushrooms can be pickled in brine into a very tasty appetizer. I like to add black peppercorns and mustard seed as well as a small garlic clove. The mushrooms will float like corks but it has never seemed to be a problem.

Summer Relish: Last summer I made a jar of relish using canned corn, chopped green tomato, red bell pepper and onion with mustard seeds. It took a month or so for the flavor to develop but I was sad when it was gone. It was long past green tomato season and I've been daydreaming about it ever since!

Pickled Garlic: Peel the cloves, fill the jar and cover with brine. It will take months (as in 4 or 5) for the cloves to ferment fully but it will be worth it. They ferment into this mellow, garlicky, almost sweet tangy condiment. Perfect for salad dressings and topping soup. And exceptionally good for you!

Of course you can mix and match. I almost never make a jar of just one vegetable, I use whatever I have around. I will often add turnips or carrots to sauerkraut, or get lazy and throw brine over cabbage as well. Give any vegetable you have a try in the brine and see how it turns out. Experiment with seasonings, garlic, onion and different flavor combinations. You'll be amazed at what you find you like. I serve pickled vegetables with almost every meal and pretty soon you will be too!

Kraut 101

I've become known in some circles as a bit of a fermentation guru. I'm no Sandor Katz, but I've done a fair amount of pickling and have a pretty decent understanding of the science of fermentation. I have been asked time and time again for help with the basics of making sauerkraut and was disappointed with some of the other kraut recipes out there. I developed this little tutorial to help the beginner kraut maker. I think it's easy, and I know it works. Give it a try.

At it's most basic sauerkraut is cabbage and salt, left to ferment into a tangy condiment. The fermentation is completed by a wide variety of bacteria that turn the sugar in the cabbage into acid that in turn preserves the cabbage from spoilage. The live bacteria in unheated sauerkraut provide immense benefit when eaten including better digestion, increased gut health and an immune system boost. I recently read that the healthy bacteria that live on your skin and in your gut outnumber your body cells 10 to 1 - doesn't it make sense to make sure they are the right kind of bacteria?

Here are my instructions for making one quart of jar fermented sauerkraut. This is a great size to start with because it is big enough for everyone to try it a couple times, but not enough that you feel overwhelmed. After your first batch, make a second and try some variations. I'll list some of those down at the bottom.

Phase one: Shopping
1. Find good quality, organic green or purple head cabbage. Look at the grocery store or at farmers markets. Even non-organic ones will ferment just fine, but buy organic if you can. One 8 inch diameter head will be more than enough, but it's not a bad idea to pick up more than you think you'll need. You can use leftovers in a recipe like this soup from Nourishin Days. Weigh your cabbage at the grocery store and remember this number.
2. Buy good quality sea salt. I use Real Salt and highly recommend it because it is "real" salt with micronutrients, but isn't going to break the bank either.


Phase two: Cleaning and Chopping
1. Get a quart size mason jar with a lid. You can either buy 6 or 12 of them new with lids, or find one at a thrift store and buy new lids and rings at the grocery store. You might even have some at home already. Wash it well with soap and hot water.
2. Core and chop your cabbage. Commercial kraut is often made with really finely shredded cabbage. I prefer a little bigger shreds.. more or less as small as I can get them with a knife.
3. As you chop your cabbage stuff it into the jar.. with no salt.. this is just for measuring. Don't pound it in, just stuff it as stuffed as you can get it. When the jar is full pull the cabbage out into the biggest mixing bowl (or a big cooking pot) you have. Add another handful or two of shredded cabbage.

Phase three: Salting and Packing
1. Remember how much your head of cabbage weighed at the grocery store? Do a little mental math estimating how much of the cabbage you used, and multiply that by 2 tsp per pound. For example, your cabbage weighed 2 pounds and you used 3/4 of the head. You used 1 1/2 pounds of cabbage so you need 3 tsp of salt. Figure out how much salt you need and sprinkle that over the cabbage. No need for a calculator here, just guestimate.
2. Toss the cabbage and the salt with your hands, squeezing and crunching the cabbage. You should start to see some liquid coming out of the cabbage. Keep kneading and squeezing, thinking about how yummy and healthy this kraut is going to be and how much you love your family for a couple minutes. Alternatively, you could pound the kraut with a wooden pounder or meat tenderizer for a shorter period of time like Jungleen is doing in this photo from Cheeseslave. Either way, the point is to allow the salt to draw the liquid out of the cabbage. Don't give yourself carpal tunnel syndrome, but do allow the cabbage to get wet.
3. Taste the cabbage.. it should be distinctly salty. If it is pleasantly salty, add some more salt. If it makes you want to gag add some more shredded cabbage :)
4. Rinse your hands off and start packing the jar. Use a wooden spoon or wooden meat pounder or small ladle to help you really pack the cabbage into the jar. You want to push any air bubbles out. Pack it in a small amount at a time until the cabbage is within 1/2 an inch of the bottom of the threads of the jar.
5. Push on the kraut one last time. If liquid isn't rising above the level of the cabbage then make a brine of about 1 tsp of salt per cup of water (this should also be too salty to be pleasant but not salty enough to make you gag). Slowly pour a little of this over the cabbage, giving it time to sink in, until it is at or above the level of the cabbage.
6. Screw the lid on tight and put in a warmish place in your kitchen. On top of the fridge, the cupboard above the microwave, etc. Do the dishes and leave the cabbage for the day.

Phase Four: Fermenting and Ageing
1. The next day, open the lid of the jar. I recommend doing this over the sink. Did the jar "pop" or fizz when you opened it? If not, that's OK. Taste the kraut. Put the lid back on and put it back in the warm spot.
2. Repeat the last step every day until it truly is popping of fizzing. Taste it again, and then put the lid back on and put that jar in the fridge.
3. Let it sit for at least one more week and then test again. Sour yet? No, let it go anothe week. In the fridge this stuff will last for weeks and months and just get sourer and sourer. Most likely after 2 weeks in the fridge it will be quite sour, but since you've been tasting it the whole time you know what it's like and when you are going to enjoy eating it. I recently found 6 month old kraut in my fridge and it was sour like vinegar pickles. The salty cabbage will eventually get sour, you just need to give it lots and lots and lots of time if thats what you want.

Phase Five: Making the next batch...
Repeat from the beginning, adding some of your sauerkraut juice to the cabbage as your are packing it or instead of the brine.

Once you get the hang of this kraut method you can start making variations. Adding caraway or juniper berries is pretty traditional, as is sliced or grated turnips or carrots. Other vegetable or seasoning options are as limitless as your imagination. Try onions, garlic, seaweed, greens like kale or brussels sprouts, roots like burdock, horseradish or beets. Try mustard seed, dill, curry or hot peppers of some sort. If you add garlic, ginger, chiles and onion you have kim chi but if you use oregano, chiles and cumin you have cortido. I recently made an apple cranberry sauerkraut that is so wonderful. Experiment, it's your kraut!
