My son loves nectarines so I bought a box of "organic" nectarines at BJs. Unfortunately, they were very sour. My mother thinks that these nectarines had been frozen at one time. I didn't want to throw them all out so I found a recipe for Nectarine Cobbler that my son absolutely loved. It comes from the Magnolia Bakery Cookbook via The Food Network.
4 cups sliced nectarines
1/2 cup cold water
1/3 cup unpacked light brown sugar
1 tablespoon cornstarch
1 tablespoon unsalted butter
1 cup all-purpose flour
1/2 cup sugar
1-1/2 cup milk
1-1/2 teaspoons baking powder
4 teaspoons (1/2 stick) unsalted butter, softened
Cinnamon sugar for sprinkling
Preheat oven to 350 degrees
To prepare the topping: In a medium-size bowl, stir together the flour, the sugar, and the baking powder. Add the milk and the butter and beat until smooth.
To prepare the filling: In a large saucepan, combine all the ingredients. Cook and stir over medium heat until mixture is thickened and bubbly, about 5-10 minutes. Pour into an ungreased 13x9-inch glass baking dish. Spoon the topping over the filling and spread carefully and evenly with a rubber spatula. Sprinkle with cinnamon sugar. Bake 30-40 minutes or until topping is lightly golden and a cake tester inserted into the center of topping comes out clean.
