My Grandmother's Recipe For Sweet And Sour Red Cabbage - a podcast by Knox Bronson ~ Riding The Wild Bubble

Slice cabbage thinly, remove white core chunks. Add everything except salt and butter to a large pot, bring to a boil over medium heat. Turn heat down and simmer for two hours, stirring as needed. Add salt and adjust vinegar/sugar proportions to taste. Add butter to taste. Do not over-cook! (Although it's not fatal if you do.)
