My Pickl-It jars have allowed me to make non-moldy sauerkraut. Hooray! I used the basic recipe for kraut from the Pickl-It website for one jar, and the other is a beet/cabbage/onion concoction that I found here. I didn't add whey, since the Pickl-It people says it's not needed for this kind of fermentation.
The verdict? The sauerkraut tastes like sauerkraut! The beet stuff is so darn sour it brings tears to my eyes and makes me cough, but the flavor is nice otherwise. Since my favorite way to eat sauerkraut is cooked in the crockpot with pork, onions, bacon, apples, and caraway, it's not practical to use this sauerkraut for that. It took several weeks to get it to this point, and cooking would pretty much make all that nice probiotic stuff obsolete.
