Saurkraut atop
Protip, btw, you can put slices of bacon or ham between the layers to gave an enhanced taste. Especially when you put ham, you can toss a whole big chunk in there and get a side dish of ham out of the same pot! Very cool.
This time I only had bacon and it needed to defrost, so I put it just under the saurkraut the next morning instead of between the layers
