ChouAmi: A New Jar-Top Fermentation Device

I am so mechanically inept that I have never been able to figure out the Kraut Source fermentation device—an expensive thing ($30!) made up of several stainless-steel parts that somehow fit together on top of a standard American mason jar. I was just as bemused when I received in the mail a ChouAmi fermentation device, which is nearly exactly like the Kraut Source device except that the ChouAmi version fits on a straight-sided, 1-liter Le Parfait jar. Such a jar was included in the package, but instructions were not.

The jar and all the stainless-steel pieces sat on the kitchen counter for months. Occasionally I would examine them and try fitting them together. Enlightenment alluded me. Then I decided use a big daikon and an Egyptian walking onion, before it went to seed, to make some kakdooki.* I looked at the Le Parfait jar. It appeared to be just about the right size to hold my big daikon. It was time to try out the ChouAmi.

Kakdooki is Korean-style fermented radish cubes, flavored with ground red pepper, green onions, garlic, sometimes ginger, and often fish sauce or tiny brined shrimp or both. This is one fermented pickle that I never bother to weight, because the seasonings seem to prevent any yeast or mold growth. Regardless, I would use my fancy new device. I mixed the radish cubes and seasonings, dropped them into the jar, and pressed down the mixture with my fingers. It fit perfectly, with just an inch or so of headspace.

trough, spring, and plateI picked up the ChouAmi pieces, and suddenly I knew exactly how they fit together. I placed the main piece on top of the jar and screwed the ring over it. Then I turned the loop in the center of the main piece. This released a spring attached to a perforated plate sized to fit perfectly in the jar (this main piece is actually three; they come apart for cleaning). The plate pressed against the vegetables, while liquid rose over it. I set the dome on top.

adding the domeOnly hours later did it occur to me that the dome wasn’t meant to keep out dust. It was sitting in a trough. So I filled the trough with water. Now I had an airlock! Carbon dioxide could escape under the dome, through the water, but oxygen couldn’t get in.

What an elaborately clever device! No wonder the price was so high.

Actually, though, I don’t know the price of a ChouAmi. The company is still getting started, through a Kickstarter campaign. The company website needs work; I couldn’t get the instructional video to play.

fermenting kakdookiSo I’m afraid that if you head to your local kitchenware store today you won’t find the ChouAmi. But the store is probably closed, anyway. So, wait until the danger of the corona virus eases, and then keep your eyes open for the ChouAmi. If you’re happy to make most of your vegetable ferments in a 1-liter jar, this device may prove to be a bon ami indeed.

Forget the Roots: Radishes for Spicy Sprouts

red-stemmed kaiware sproutsThese are red-stemmed kaiware, radish sprouts, growing in one of my raised beds last September. I thank Judy Gregory for sending me the seeds. She got them from Kitazawa Seed Co., of Oakland, which has been selling Asian seeds in California since 1917 (except for a three-year break during World War II, when the Kitazawa family members were confined in concentration camps).

Kitazawa’s online catalog currently lists eight radish varieties for sprouting, in various colors from all-green to all-purple; two other varieties for their developed leaves (ha daikon); and thirty-seven for their roots, from round to tapered and from small (such as French Breakfast) to monstrous (Sakurajima Mammoth, which can reach 100 pounds). Although kaiware and ha daikon are of the same species, Raphanus sativus, as all of the root radishes, the roots of kaiware and ha daikon do not swell.

Kaiware are so delicate that they are always eaten raw. In the Japanese tradition they embellish sashimi and sushi, and at any table they can add a mildly pungent, crisp element to salads, sandwiches, and soups.

After going away for a few weeks, I had big leaves to harvest. Unlike the prickly leaves of cherry radishes, these were tender enough that we could enjoy them raw in salads. We cooked some, too, just as we might cook mustard or beet greens.

flowering radishAlthough I’ve now started a fresh kaiware patch, the original one lasted through the winter, under plastic. We would still be eating from the same patch, in fact, except that I’m now letting it go to seed. Unlike many of the root radishes in the Kitazawa catalog, the kaiware varieties are all non-hybrids, so I plan to keep the seeds in the hope that we can continue eating kaiware indefinitely. As for the money I’ll save, I may well spend it on seeds of some other amazing vegetable variety from Kitazawa.
