Step 1

Preheat oven to 400 degrees F (200 degrees C).

Step 2

Combine 1/2 cup sugar, cornstarch, and cinnamon in a saucepan and whisk to mix. Stir in sliced peaches (see Editor's Note) and lemon juice, tossing until peaches are evenly coated.

Step 3

Cook filling over medium heat, stirring constantly, until mixture thickens and boils. Boil 1 minute. Pour mixture into an ungreased 2-quart casserole dish. Keep mixture hot in oven while you make the topping.

Step 4

In a medium bowl combine flour, 1 tablespoon sugar, baking powder, and salt. Mix thoroughly, then cut in shortening until mixture looks like fine crumbs. Add milk and stir until mixture is evenly moistened.

Step 5

Remove peach filling from oven and drop dough onto peaches in 6 equal-size spoonfuls.

Step 6

Return cobbler to oven and bake until topping is golden brown, 25 to 30 minutes.
