We inherited a bunch of big crocks and I really want to! It sounds like you need cabbage, salt, something heavy and time, right?
There's a story about my husband's cousin's FIL. I guess all of these old German guys get together every year and buy a truck full of cabbage and spend the day making kraut together.
I've quizzed my gmil and she dismissed it as something very simple and easy to do.
I run the Frontier Wholesale co-op in February, May, August & November
