Potato-Filled Vareniki or Pierogi
My favorite dumplings, these are creamy, savory, and salty and, when served with the cooked onion garnish and some sour cream, irresistible. Like the cheese filled version on page 60, they may be boiled and served with melted butter, but I think they’re best when fried in butter and served with sour cream. In addition to the variation, you can stuff these with cooked cabbage, cooked mushrooms, sauerkraut, or almost anything else you can think of.
