When my friends Wendy and Greg handed me a gorgeous, huge red cabbage from their garden a couple of months ago, Greg told me he loves to make red-cabbage sauerkraut. The Pickle Lady was humbled; I’d never made or even tasted sauerkraut from red cabbages! Now I knew what I would do with my beautiful cabbage.
I decided to take as my model a low-salt red-cabbage sauerkraut recipe from an odd little Canadian cookbook, Making Sauerkraut and Pickled Vegetables at Home. I cut the head fine, using a mandoline, and mixed the shredded cabbage with some apple and onion slices, a bay leaf, caraway seeds, and juniper berries. As always in making sauerkraut, I tossed the mixture with salt and packed it firmly into a crock. But several hours later the cabbage had released almost no juice. This was problematic; when you’re making sauerkraut, the cabbage must be well covered with liquid to keep from rotting. The Canadian authors, warning that red cabbage is “a very hard vegetable,” suggested pressing “thoroughly with a potato masher,” but this didn’t work for me. I could have added some brine from one of the big jars of fermented pickles in my garage refrigerator, following another suggestion from the Canadian authors, but then the sauerkraut would have tasted of dill and garlic. A final suggestion from the Canadians was to add whey, strained out of buttermilk or kefir, which they said would jump-start the fermentation. That sounded to me like an unnecessary bother. So I decided to add fresh brine–that is, salted water.
Two weeks later, I pulled from my crock heaps of gloriously hot-pink, tart, delicious sauerkraut. Here’s the recipe. You can add more spices or leave them out, as you prefer.
4 pounds finely shredded red cabbage, plus a few whole outer leaves
1 large apple, cored and sliced thin
1 medium-large onion, sliced thin
1 Mediterranean bay leaf
Pinch of caraway seeds
3 juniper berries
3 tablespoons pickling salt (fine, pure salt)
1 quart water
In a large bowl or stockpot, thoroughly mix the shredded cabbage, apple, onion, bay, caraway, juniper berries, and 1½ tablespoons salt. Pack the mixture firmly in a crock or gallon jar. Wait an hour or two for the salt to dissolve.
Stir the remaining 1½ tablespoons salt into the water, and keep stirring until the liquid is clear. Pour the brine over the cabbage mixture. Lay the whole cabbage leaves on top, and add weights. (I used the weights that come with a Harsch pickling crock. With an ordinary crock, cover the cabbage with a plate that just fits inside the crock, and weight the plate with a capped, water-filled glass jar. If you’re using a gallon glass jar, weight the cabbage with a freezer-weight plastic bag filled with brine in the proportion of 1½ tablespoons salt to 1 quart water.) The cabbage mixture should be well covered with liquid. If it isn’t, add more brine in the same proportion. Keep the crock or jar at warm room temperature for two to three days, until fermentation gets underway, and then set it in a cooler place. If you’re using an ordinary crock, you’ll need to skim the brine occasionally.
Begin tasting the sauerkraut after two weeks. When it’s as sour as you like, transfer it to a clean jar, and store the jar in the refrigerator. If you like, you can freeze some of your kraut in plastic bags, rigid plastic containers, or glass jars. I don’t recommend canning it. Although with the addition of brine my recipe is saltier than the Canadians’ version, the sauerkraut will still be less salty than the USDA approves for canning.
