Fermenting, Well Beyond Yogurt and Cheese

Eating in Season with Jacqui Marsh

Hi there. That's my cow Nutmeg posing with me in the little picture—isn't she a looker?? She's responsible for all the dairy products of our household, and she takes her job very seriously. When I got her, I immediately became interested in the fermentation of milk into cheese, yogurt, cultured butter and the like, but I never gave too much thought to the fermentation of anything else. And there is so much else that can be fermented! Vegetables, fruits, dried beans, fish, meat, herbs, and a dozen other categories.

When I read Nourishing Traditions (Sally Fallon) and Wild Fermentation (Sandor Ellix Katz) I became fascinated by the possibilities of this amazing method of food preservation and I got started on a delightful experiment that picks up a little more steam every year.

I can't give you the equation that explains how putting cabbage, salt and (sometimes) water in a jar gives you a crunchy, deliciously sour pickle several weeks or months later, but I can address the question that I had: “Why doesn't it rot?” The (very) basic answer is that this nifty thing called lactic acid is produced during the breakdown of organic material. Salt helps the process along. To steal an explanation from Sally F.: “Lactic acid is a natural preservative that inhibits putrefying bacteria. Starches and sugars in vegetables and fruits are converted to lactic acid by the many species of lacticacid- producing bacteria. These lactobacilli are ubiquitous, present on the surface of all living things and especially numerous on leaves and roots of plants growing in or near the ground.” (They're also amazingly beneficial for our gut flora). Once there is a buildup of that lactic acid in your pickle, it provides as acid an environment as any vinegar pickle and does just as good a job at keeping that food fresh.

I have found lacto-fermenting about twenty times faster and easier than vinegar pickling and heat processing. My mother would be in the kitchen until all hours of the night: stove on high, steaming pots processing finished jars, the next brine boiling on the stove. Those pickles were delicious, to be sure, but I can't help but compare how Fermenting, Well Beyond Yogurt and Cheese I got my cukes and cabbage preserved last year. The stove never got turned on. I just washed my jars, chopped my vegetables, salted and packed. If it were a particularly hot and nasty day, I took my task to the basement, and cooled off as I worked. No sweating over a hot stove in ninety-degree heat that day. It baffles me how we moved from a fairly simple process of throwing vegetables in a crock with salt to burning a buttload of electricity and pushing our endurance in the kitchen, warming kitchen and planet…

I find lacto-fermented vegetables wonderfully crunchy, raw and fresh in the winter. I frequently use salsa as a “fresh” tomato on a winter spinach salad, kimchee is dynamite with eggs in the morning, hot peppers are incomparable for cooking Indian or Mexican dishes and cucumbers make winter sandwiches as good as summer ones, and the brine from any of them can be used as a healthful vinegar substitute in salad dressing or just drunk as a spicy juice.

I've never had any problems with spoilage of my pickles except when whole cucumbers have popped up out of the brine and gotten soft and squishy before curing. But from what I've heard, if your pickles go bad—you know it! They stink, are black and slimy and few would be tempted to put them in their mouth. But let me pass on some excellent advice from Sandor Katz. “Usually I find that [any] funkiness is limited to the top layer, which is in contact with the microbe-rich air. Underneath that the ferment is fine. If in doubt, trust your nose…. If you're still in doubt, taste just a little bit. Mix it with your saliva and swish it around your mouth like they do at wine tastings. If it doesn't taste good, don't eat it.” I hope you will be tempted to try a new method for your pickling—and keep a centuries old method alive and well.

Kimchee (adapted from Nourishing Traditions by Sally Fallon)
1 head cabbage (I prefer purple cabbage as it is crunchier than green)
1 bunch green onions
1 cup carrot grated
1/2 cup daikon radish, grated (optional)
1 tablespoon freshly grated ginger
3 cloves garlic peeled and minced
1/2-1 tsp dried chile flakes (or any number of fresh that you would like!) coarse sea salt
Weigh your bowl before you start!
Place all ingredients except salt in bowl and pound with a wooden pounder to release juices. Weigh finished product in the bowl and add 2 tsp of salt per net pound of vegetables. Toss well to incorporate salt. Place in a mason jar—I prefer regular size mouth as it limits air contact and seems to keep the contents from floating up above the brine so easily. Pack the vegetables down into the jar with a fork until the juice rises to cover them by at least 1/2 to 3/4 inch. If you haven't produced enough juice for that to happen, you may add a bit of unchlorinated water to top it up. Cover tightly and keep at room temperature for three days before transferring to cold storage. You can sample at any time after three days, but really, it is best after at least a month.

• Don't worry if you don't have every last ingredient, and don't be afraid to add another. I sometimes add kelp flakes, cumin seeds, or nasturtium seedpods.

• I like the old fashioned glass topped mason jars for this job, as the salt in the pickle does not corrode the glass and rubber that it comes in contact with. If you have bail-top jars—now's the time to put them to work.

• Sally recommends that one store their pickles in the refrigerator after the first three days. I have not found this to be necessary, indeed, it misses the point. I have always just moved my pickles to my cool basement right after jarring them and they have kept well for up to a year.

Pickled Hot Peppers Pack a Mason jar with small hot peppers. Add 1 tablespoon sea salt to pint (2 to a quart) and fill to within an inch of top with unchlorinated water. Carefully pack a grape leaf down over them, pushing the edges of the leaf into the sides of a jar with a chopstick or some other dull weapon so as not to puncture the leaf. Goal is to use leaf to hold the whole fruits below the brine by a half-inch or so to keep peppers from spoiling. The grape leaf also contains tannin, which helps to preserve crunchy qualities. Use these wonders
