2Remove from stove and stir in flavoring and cornstarch mixture.(make sure to mix the cornstarch with cold water) Pour into a greased 8x8 dish.
3Roll and cut pastry to fit in a latice fashion.
Use extra crust to put into peach mixture. Just be sure to get the extra pastry covered with juice. Bake at 400 degrees until cobbler is bubbly and the crust is brown.
