No need to add any vinegar! Salt alone preserves sour cabbage very well. I add 1/4 cup of shredded carrot for colour. Sometimes, I add a laurel leaf and 1/2 teaspoon of caraway seeds.
Ach du lieber! Does sauerkraut not come in a clear glass jar off the grocer's shelf any longer? A dying art. Made for PAC Fall 2011.
