Kluski śląskie are the soft, springy Silesian potato dumplings with the famous dimple in the middle. Mashed potato, potato starch and an egg, shaped, simmered gently and tossed in butter: made for gravy.
Keep the water at a gentle simmer, never a rolling boil, or the dumplings can break apart before they set. The dough should feel like modelling clay: sticky means more starch, crumbly means the second egg. Makes about 40 dumplings. Freeze extras raw on a tray, then bag; cook from frozen.
