Sauerkraut Failure

Well, the fermented cabbage that I was trying to make sauerkraut out of turned out slimy, dark brown and nasty (and stinky!) I had to throw the whole thing out.  I'm not deterred though, I will try again.  I think I need to buy an actual crock to ferment in, because I had a hard time keeping the cabbage down below the brine in the jar because of the curves.  

 I'll be looking for a crock and try again!
