In a large mixing bowl, combine the flour, salt, and baking powder.

Gradually add water and melted butter to the dry ingredients, mixing until a dough forms.

Knead the dough for about 5 minutes until smooth.

Let the dough rest for 10 minutes.

Roll out the dough on a floured surface using a rolling pin to about 1/4-inch thickness.

Cut the dough into small squares or circles.

Bring a pot of water to a boil.

Drop the dumplings into the boiling water and cook for 10-15 minutes until they float to the top.

Use a slotted spoon to remove the dumplings from the pot.

Serve hot with your choice of sauce or gravy.
