Finely dice the onion and garlic and sauté the bacon in some rendered fat. Dice the smoked bacon and mix with the onions and spices. Shape the mixture into dumplings the size of a golf ball and freeze briefly.
In the meantime, make a firm dough out of flour, water, oil and salt. From this, separate pieces that are slightly larger than the filling and press flat. Cover the cooled meat mixture with the batter and press firmly. Cook gently in salted water for about 20 minutes, until the dumplings rise to the surface.
