I didn't add radish, used scallions instead of leeks and added tomato sauce rather than tomatoes, so I didn't exactly follow the recipe. However, this was delicious. The sour cream makes this taste especially wonderful!
Made this with veggie stock but otherwise followed the suggested ingredients -- very yummy and comforting. Hardest part was shredding the cabbage. :) Definitely tasted better the next day!
Absolutely phenomenal! By far my new favorite soup! Dark rye bread is recommended for dipping. We used chicken stock - I'm allergic to beef. We added a pound of sausage in step 2. We also used 2.5 lbs cabbage instead of 1.5 lbs, and 7 red potatoes (skin on) instead of the 3 medium potatoes.
