In a large mixing bowl, combine flour and salt.

Add the egg and water to the flour and mix until a dough forms.

Knead the dough on a floured surface for about 5 minutes until smooth.

Cover the dough and let it rest for 30 minutes.

Roll out the dough to about 1/8 inch thick using a rolling pin.

Cut the dough into 3-inch squares.

Place a few cherries in the center of each square and sprinkle with sugar.

Fold the squares into triangles and press the edges to seal.

Bring a pot of water to a boil and gently drop the dumplings in.

Cook the dumplings for about 10 minutes or until they float to the surface.

Use a slotted spoon to remove the dumplings and place them on a plate.

Melt the butter in a small pan and toast the bread crumbs until golden.

Drizzle the melted butter and toasted bread crumbs over the dumplings.

Sprinkle with powdered sugar before serving.
