Step 1Grease an 11-by-7-inch baking dish and set aside.
Step 2Combine the apples, granulated sugar, flour, cornstarch, lemon zest and juice in a bowl and stir to mix. Pour into the prepared baking dish.
Step 1Heat the oven to 375 degrees.
Step 2Combine the flour, brown sugar, oatmeal, almonds, cinnamon, cloves and salt in a large bowl and stir to mix.
Step 3Add the butter and cut it into the mixture with a pastry blender or 2 knives until the mixture resembles coarse meal.
Step 4Sprinkle the topping over the apple mixture. Bake until the fruit is bubbling around the edges and the top is crisp and golden brown, 40 to 45 minutes. Cool slightly before serving. Serve warm.
Strawberry-rhubarb crisp: Substitute 2 cups hulled, halved strawberries and 4 cups chopped rhubarb for the apples. Decrease the granulated sugar to 1 cup, or, for a sweeter crisp, use the 1 1/4 cups.
