I make sauerkraut soup. (I think it must be Slovenian. recipe from my MIL)
Use leftover ham with bone or ham hocks
2 large cans sauerkraut (I rinse one and do not rinse the second one so I get some zing!)
Water to cover everything in dutch oven
Cook for 3 or 4 hours
Add 3 cut up potatoes and cook for another hour or till potato is tender
This is one of our favorite recipes for winter especially! Enjoy
