Recently, my interest in homemade ferments and high quality cooking fats has taken off! This year, I have rendered lard from pastured pig fat, made my own ghee, and gotten into fermenting. So far, I have made yogurt, probiotic ginger ale, sauerkraut, and ginger carrots. There's something very satisfying about chopping a head of cabbage, adding salt, pounding it, leaving it alone for a week, and coming back to sauerkraut. It's incredibly easy and economical, especially considering that live sauerkraut is $11 for a 12 oz jar at Whole Foods. My method is based on the book Wild Fermentation by Sandor Katz. You can find his method and a forum at www.wildfermentation.com.
Here are the basic steps. Once I figured it out, it took me all of ten minutes!
Here are the basic steps. Once I figured it out, it took me all of ten minutes!
Chop a head of cabbage. Add it by handfuls to a large bowl or crock, and sprinkle sea salt over each new handful. Pound for a few minutes using a potato masher. The pounding and salt will start to leach the juices out of the cabbage, forming a brine that lets the good bacteria grow but kills anything pathogenic. Then, you need to tightly seal the cabbage in your container with a lid of some sort. I found a plate that is about the right size. The first two times I made it, I didn't have enough cabbage, so I shredded some carrots. It worked out great. This time, I used an entire head of green cabbage and it was the right amount for my equipment.
Put a weight on the plate (a full Nalgene works), and cover it with a towel to keep the dust out. It's Ok if there is a little space around the sides, but you want a fairly tight seal. For the first few days of aging, push the weight down gently every few hours or whenever you think of it; this helps squeeze the water out of the cabbage and form more brine. By using the weight, you don't need to do as much pounding. My sister uses her food processor to chop the cabbage, and reports that this works well, too.
After a day or two, the brine will rise up to the plate, sealing the cabbage in. The good bacteria will be growing and transforming your cabbage into kraut. I check it every few days to make sure the brine is still high enough. You can add some salt water if you don't get enough liquid. Six to seven days of aging seems to be the optimal timeframe for our taste and patience. The smell will be startlingly tart and sharp at first, and I admit that it was a little scary the first time! After all, you're colonizing bacteria in your kitchen, something that is counter-intuitive in our germ-o-phobe culture. Don't worry, though: the experts say that you will know if your ferment has gone bad. It supposedly becomes black, moldy, putrid, etc. A little funk is to be expected, but it mellows out and becomes that familiar tangy smell/flavor, especially after it's been put into the fridge. It will stay good in the fridge for months, but we're lucky if it lasts a week.
My interest in fermented foods ties in to my journey towards strengthening my immune system. Recent research is showing that much of our immune system is in our gut, and that if we can colonize ourselves with good bacteria, we have a much better chance of fighting off the bad ones! Last year, I had a terrible string of colds and viruses, probably due to the fact that I work with kids in a music school with little air circulation and hundreds of people coming in and out every week. I was eating a pretty good "real food" diet, but something was still missing - I was continually sick, and as a result basically had no race season. Since, I have added fermented cod liver oil, occasional epsom salt baths, Vitamin D, therapeutic strength probiotic supplements, and--you guessed it--lots of fermented foods. I happy to report that things have been improving noticeably. I have still been getting colds here and there, but they are much milder and shorter. Recently, I kicked a cold in two days, when before they'd drag on for weeks! Hopefully things will keep moving in the right direction so I can have a strong, virus-free race season.
Well, that's one post. I guess I have gotten behind with blogging! There is more to catch up on: the start of race season, how the Alexander Technique has led to more freedom of motion in my playing and teaching, and some remaining articles about bicycle touring in Europe. Stay tuned!
