- 1½ pounds russet potatoes cooked in their jackets, peeled and mashed (685 g)
- 1 large beaten egg
- ½ teaspoon salt or more to taste (1.25 g or more)
- Approximately 2 cups all-purpose flour (240 g)
- Polonaise Topping (optional): 3 tablespoons butter (45 g)
- 3 tablespoons fresh white breadcrumbs (45 g)
- Place mashed or ground potatoes in a large bowl. Stir in egg, salt and as much flour as necessary to form a smooth and firm dough. Avoid adding too much flour, this might stiffen the dough.
- Bring a large saucepan of salted water to a boil. On a lightly floured surface and using your lightly floured hands, shape pieces of dough into cylinders with ½ inch thickness.
- Drop dumplings by tablespoons into the boiling water (in batches to avoid crowding) and allow simmering.
- Reduce heat and cook 1 to 5 minutes. Remove one dumpling with a slotted spoon to check if it is already cooked. Using a slotted spoon, transfer cooked dumplings to a strainer and drain.
- To serve dumplings with Polonaise topping, melt the butter in a small skillet. Add the breadcrumbs and fry for about 3 minutes or until golden brown.
- Place drained dumplings to a serving dish and sprinkle the buttered breadcrumbs on top.
