DOUGH
3 cups all-purpose flour

Recipe
Sift flour and baking powder into a bowl. Stir in salt. Add water, egg and 1 tablespoon oil. Stir with wooden spoon until dough holds together. Turn onto a lightly floured board and knead until smooth and elastic. Using only enough flour to prevent dough from sticking, about 5 minutes.

For each filling, roll out 1/4 of dough on a lightly floured surface to a 12 inch square. With a sharp knife, cut in half to make 2 six inch wide strips. Brush lightly with oil, Spoon filling down center of each strip, dividing evenly. Bring one side of pastry over filling, then roll to enclose filling completely. Pinch ends together. Place on a lightly greased cookie sheet, seam side down. Score with a blunt edge of knife at 1 inch intervals, do not cut through. Brush with egg yolk mixture. Bake in a 375 F oven 30 minutes or until golden brown. Cut into 1 inch pieces for serving.
