The main problem I had was finding containers heavy enough to tamp down the cabbage and yet slender enough to fit in the mouths of my jars (the water-filled bags did not work for me). A can of tomato paste and a jar of olives.
So, I would like a crock. Because at $1.25 for a huge cabbage, I will be making sauerkraut again.
The flavor is wonderful. I froze some sauerkraut in pint jars, thinking happily of reubens.
