We made a version of this at a family get-together and tried it again the other day. The cayenne is good but make sure to add it according to your taste. The original recipe calls for tamari to taste as well, but we didn't use it. (I think tamari is a particular kind of soy sauce).

A Ukrainian dish usually served either boiled or fried with onions and topped with sour cream.  I don't know what a true Ukrainian would say about our method.  Elbert really likes these.
