Assembling the Sanbusa

 * 1) Preheat the oven to 350°F degrees.
 * 2) For each pastry, take a walnut-sized piece of dough and roll it out into a 3-inch circle.
 * 3) Place a teaspoonful of filling in the center of the dough, fold the circle into a half-moon shape and pinch the edges firmly. (Another traditional shape is the triangular pocket, formed by pinching together the edges of the circle in three seams that meet in the center over the filling).
 * 4) Place the pastries on an ungreased baking sheet and bake in the oven for 45 minutes, until golden yellow, or deep fry in vegetable oil.
 * 5) Serve warm.
