Pour flour in a mound on the counter. Make a whole in the centre. Sprinkle in salt & baking powder. Add 1/2 the water & with your hand, mix the water & the flour. Add the rest of the water & continue to work until the dough is smooth. Knead well for 5 minutes. Cover & set aside for 30 minutes. Knead dough on well floured surface. Roll into a long sausage shape about 1" in diameter. Cut into pieces 1" wide. Dust with flour & flatten each
piece into a round. Roll each round with your hands until you have a perfect circle of 3" to 3 1/2" & the thickness of a coin. Fill with the filling of your choice. Betty Jung, "The Kopan Cookbook"
