This tastes great served hot over vanilla ice cream.
The choice of fruit can vary, apples and peaches are especially suited for crumbles, you can add spices accordingly such as cinnamon, ginger or nutmeg. You can also add 1/2 cup of old-fashioned rolled oats or 1/2 cup chopped nuts (or both) to the topping.
Crumbles will keep, covered and refrigerated, for up to 1 week. Serve cold, room temperature, or re-warmed in a low oven for 20 minutes.
