How To Make a Fruit Crumble with Any Kind of Fruit

Step 1

Heat oven to 375°F and prepare the baking dish. Arrange a rack in the middle of the the oven and heat to 375°F. Coat a 9x9-inch or 11x7-inch baking dish with butter; set aside.

Step 2

Prepare the fruit filling. If necessary, dice the fruit into bite-sized pieces, removing any stems, seeds, or inedible parts. Toss the fruit with sugar, lemon juice, cornstarch, and any spices in a large bowl. Use more sugar and less lemon juice when cooking with tart fruits, like rhubarb and blackberries, and less sugar but more lemon juice for sweet fruits, like peaches and plums. Best is to taste a piece of fruit and adjust to taste. Use more cornstarch with very juicy fruits like plums and less with firm fruits like apples. But don't worry — no matter your ratio of these ingredients, your crumble will be delicious.

Step 3

Pour the fruit filling into the baking dish. Transfer the fruit filling into the baking dish.

Step 4

Prepare the crumble topping. Whisk the flour, sugar, cinnamon, baking powder, and salt together in a large bowl. Cut the butter into a few large pieces and toss these in the dry ingredients. Using your fingers, a fork, or a pastry cutter, work the butter into the dry ingredients until large, heavy crumbs are formed.

Step 5

Scatter the crumble over the fruit. Pour the crumble topping evenly over the fruit.

Step 6

Bake the crumble. Bake until the fruit juices are bubbling around the edges of the pan and the topping is firm to the touch, 30 to 35 minutes.

Step 7

Cool the crumble. Let the crumble cool for at least 15 minutes before serving. If transporting to a picnic or party, let the crumble cool completely to give the fruit filling time to set.
