This popular Polish dish has been variously translated by English speakers as dough pockets, filled dumplings and even ‘Polish ravioli’. Pierogi can have a variety of fillings, but the most common are minced cooked meat, sauerkraut & mushrooms, cheese and potatoes (these are known as ruskie "Ruthenian" pierogi), sweet cheese (usually with a touch of vanilla) and blueberries (in summer). Other fillings include buckwheat groats, potatoes & onions and lentils. Toppings include fried fat-back nuggets, sour cream, melted butter or butter-browned bread crumbs. Singular: pieróg.
