Start your grill. For charcoal, bank a chimney full of hot coals off to one side, leaving the other side free of any coals. For gas grills, light only one side of the burners. Mix up the batter:
- 1/2 cup flour
- 1/2 cup sugar
- 1/2 Tablespoon baking powder
- pinch of salt
- 1/2 cup of milk
Melt a half-stick of butter in an 8 x 8 pan. Gently pour in the batter. Do not spread or mix it. Let it flow to the edges as you bring the following to a boil in a saucepan:
- 2 cups peach slices
- 1/2 cup blueberries
- 1/2 cup sugar
- 1/2 tablespoon lemon juice
Pour this over the batter. Sprinkle some cinnamon over the whole thing, and place the pan on the grill opposite the hot coals or burners. In about 45 minutes, or when the batter has browned or passes the clean toothpick test, it’s done. Rotate the pan 180-degrees midway through the cook for even cooking. Serve hot with whipped cream or ice cream.
