2 cups unbleached flour
1/2 tsp salt
1 large egg
1/2 cup sour cream
2- 4 tbsp water
Place the flour, egg, salt and sour cream into the bowl of a food processor fitted with a dough blade. Pulse a few times. If the dough doesn't form into a ball and pull away from the sides, then add a tablespoon of water at a time until it does. You want a soft, slightly sticky dough.
Process the dough for a few seconds, then place it into a buttered bowl and cover with a damp kitchen towel while you make the filling.
Filling: Fresh cherries, pitted (I use this technique!)
