Roll out the dough and cut a circle out of it in a wide round container.
Make a "sausage" out of the remaining dough and stick it around like a board, after transferring the dough to a baking sheet covered with foil and sprinkled with flour.
Evaporate the lingonberries with the addition of sugar in a frying pan.
Put the lingonberries on the dough and brush the sides with an egg.
Send to the oven preheated to 200 C until the dough appears golden brown. The lingonberry pie is ready. Allow to cool slightly and can be served.
