You decide how much you make.
Make the pastry dough and roll out to about 1/4" thick.
Cut out rectangles.
Add jam or fruit filling to bottom and cover with top rectangle like a sandwich.
Use a fork to crimp the edges together.
Bake on 325°F. For wheat flour, it's best to take a listen or tap to see if baked done as color stays consistent throughout baking process.
For jam: crush raspberry with bowl and spoon or mortar and pestle and add a small amount of water.
