Bare pancakes don't cut the mustard. Poland is full of nice sauces.
You're right, they are better with a sauce. Garlic and herb, mushroom, who knows. ;)
you can just put some sugar on it
I heard that a few times and tried it once. I don't like it and can't understand why sugar on top is used. It's a strange addition. Oh yes though, nice with Hungarian Goulash! YUM! :D
