I watched my inlaws make sauerkraut for years, but this was my first time making it on my own.
I filled an 8 gallon crock to within about 6 inches of the top (5 lbs shredded to 3 tbs canning salt), mashing each batch with a wooden spoon to release their water. I covered it with a damp white cloth, placed wooden boards on top, a plate on top of the boards, then topped it off with a huge rock. Ended up with about 3 inches of juice on top.
It foamed up for about a week, then stopped foaming (I skimmed it almost every day, then replaced the rag and cleaned everything once a week), and started building a filmy scum that smells like yeast. Is this normal, or should I be worried? This Friday will be 3 weeks since I made it.
