Look out, Sandor Katz. I read your book.
Actually, I use his work as reference, as well as many good (and a few dubiously gushing) Web sites to guide me as I learn the arts of lacto-fermentation. What, pray, is that?
You've eaten fermented foods your whole life, if you enjoy kimchi you've had it. Likewise sauerkraut, if it came from someone's kitchen and not a factory jar.
Wikipedia's definition, however, seems to come straight from a high-school chem lab, so I'll try some of the fermentation-fanatic sites for a warmer vibe. Here's a nice definition by Danielle at Fermented Food Lab:
Lacto-fermentation is the oldest form of food preservation in the world. It involves only salt, water and vegetables. The salt water brine creates an anaerobic environment (free of oxygen) where only lactobacillus bacteria can survive. The lactobacillus bacteria act as a preservative, keeping harmful bacteria from living in the ferment.
Yes, I too was dubious about this entire business, imagining a lingering death. I've drunk kombucha, mostly out of courtesy to those insisting it is the drink of immortality. Save for one or two times, I found it dreadful.
My purpose in fermenting things has been to make great ice-box pickles, kraut I can, and the holy grail: golden pepperoncini, my food of the gods. This season I fermented other peppers, notably jalapeño slices and Thai Dragons (whole). For really hot peppers of that sort, fermenting takes the edge off the heat.
I don't offer recipes here. To get started, however, you can consult my gold standard: The National Center for Home Food Preservation. No New-Age mysticism or miracle cures there, just trustworthy advice that will not make you sick. Start there for pickles and kraut and basic how-tos. After that, venture into the briny wilds of the Interwebs. Experiment, carefully.
Suffice to say I've learned a few things:
- Adding a grape leaf to the fermenting crock helps keep veggies crisp.
- Fermented foods store in the fridge a long time. I do add a bit of vinegar to the top of the jar, heresy to some who ferment but one of my favorite ingredients. My kitchen, my rules.
- Hot, humid weather really shortens the time needed. My ferments in Fall take take several more days. Keep the crocks away from sunny windows, in any case.
- Brine matters. I found an excellent online calculator you might wish to try, to get the right percentage of brine for your crock.
- Cheap Morton Kosher or Pickling salts are excellent. Perhaps pricey sea-salt would change things, but my uncultured palate barely can sense a difference. Just do not use iodized salt.
If you find a good recipe for crisp, flavorful okra, let me know. That was my only fermenting failure this year. And how I love okra.
