Its like a southern relish/sauerkraut condiment. There's several ways to make it. I use cabbage, green tomatoes, onion, spicy peppers or bell peppers, mustard and celery seed, vinegar and tumeric boil it for a few minutes, and can, is how I make mine.

It's meant to be a pickled relish made with the end of season's harvest. Green tomatoes, cabbage, onions, green peppers, beans (green and/or bush) - it's all fair game. Seasoning tends to be minimal - salt, pepper and maybe some pickling spices. Grandma Duck made a sweet version - I didn't care for it. Consequently I shied away from it for decades until I tried a neighbor's version that was more savory.

So it can run the gamut flavor wise.
