Crisp: A baked fruit dessert with a streusel topping (also called a crumble)
1. In a medium bowl, combine 3/4 cup flour, 3 Tbs. light-brown sugar, 1 Tbs. sugar, and 1/4 tsp. salt. Work 6 Tbs. unsalted butter, cubed and softened, into mixture by hand until crumbly. Stir in 1/2 cup rolled oats.
2. In a large bowl, combine 6 cups fruit (peeled and chopped if necessary), 2 to 4 Tbs. sugar (depending on sweetness of fruit), 1 Tbs. cornstarch, 2 tsp. vanilla, juice of half a lemon, and 1/8 tsp. salt.
3. Preheat oven to 375 degrees F. Transfer filling to a buttered 8-cup baking dish, and crumble topping over it. Bake until topping is golden and filling is bubbling, about 45 minutes. Let cool 20 minutes.
