Ingredients

　　2 cups blackberries, picked over and rinsed

　　1 tablespoon cornstarch

　　2 tablespoons fresh lemon juice

　　1/3 cup granulated sugar

　　2/3 cup all-purpose flour

　　3/4 cup firmly packed light brown sugar

　　1/2 cup old-fashioned rolled oats

　　1/2 teaspoon salt

　　1 teaspoon cinnamon

　　1/2 teaspoon freshly grated nutmeg

　　3/4 stick (6 tablespoons) cold unsalted butter, cut into bits

　　3/4 cup coarsely chopped lightly toasted pecans

　　peach and brown sugar ice cream or vanilla cream as an accompaniment

　　In a large bowl toss the peaches and the blackberries gently with the cornstarch, the lemon juice, and the granulated sugar until the mixture is combined well. In a small bowl stir together the flour, the brown sugar, the oats, the salt, the cinnamon, and the nutmeg, add the butter, blending the mixture until it resembles coarse meal, and stir in the pecans. Spread the peach mixture in a 13- by 9-inch (3 quart) baking dish, sprinkle the pecan mixture evenly over it, and bake the crisp in the middle of a preheated 350°F. oven for 45 to 50 minutes, or until the top is golden. Serve the crisp with the ice cream.
