Blueberry Cobbler
Adapted from Cook's Illustrated.
Serves 6 to 8
Filling
36 ounces frozen blueberries (about 6 cups), preferably wild
1/2 cup granulated sugar (3 1/2 ounces)
1 tablespoon cornstarch
pinch ground cinnamon
pinch table salt
1 1/2 teaspoons grated lemon zest
1 tablespoon lemon juice
Biscuit Topping
1 cup unbleached all-purpose flour (5 ounces)
2 tablespoons stone-ground cornmeal
1/4 cup granulated sugar plus 2 teaspoons for sprinkling
2 teaspoons baking powder
1/4 teaspoon baking soda
1/4 teaspoon table salt
4 tablespoons unsalted butter (1/2 stick), melted
1/3 cup buttermilk
1/2 teaspoon vanilla extract
1/8 teaspoon ground cinnamon
1. Thaw frozen blueberries in colander, allowing liquid to drain away.
2. Adjust oven rack to lower-middle position and heat oven to 375 degrees.
3. For the filling: Stir sugar, cornstarch, cinnamon, and salt together in large bowl. Add berries and mix gently with rubber spatula until evenly coated; add lemon zest and juice and mix to combine. Transfer berry mixture to 9-inch glass pie pan, place pie pan on rimmed baking sheet, and bake until filling is hot and bubbling around edges, about 30 minutes.
4. For the biscuit topping: Whisk flour, cornmeal, 1/4 cup sugar, baking powder, baking soda, and salt in large bowl to combine. Whisk melted butter, buttermilk, and vanilla in small bowl. Mix remaining 2 teaspoons sugar and cinnamon in second small bowl and set aside. One minute before berries come out of the oven, add wet ingredients to dry ingredients; stir with rubber spatula until just combined and no dry pockets remain.
5. To assemble and bake cobbler: Remove berries from oven; increase oven temperature to 425 degrees. Pinch off 8 equal-sized pieces biscuit dough and place on hot berry filling, spacing them at least 1/2 inch apart (they should not touch). Sprinkle each mound of dough with cinnamon-sugar. Bake until filling is bubbling and biscuits are golden brown on top and cooked through, 20 to 22 minutes. Cool cobbler on wire rack 20 minutes and serve.
