Add enough flour to make a dough thick enough that can be rolled out, a shake of Salt and Pepper added to flour. Roll out on floured board, then cut in oblong pieces then roll each oblong piece into kind of a horn shape by putting a thumb on a corner and roll around.

These can be added to soups or broths - cook covered about 7 minutes till they come to top.
