Make crumble filling: Mix the cherries and apples with sugar, lemon juice, and a few tablespoons of water or apple juice. Let it sit while you prepare the rest.2 tablespoons granulated sugar + juice of ½ lemon + 3-4 tablespoons apple juice
Make the crumble: Combine flour, butter, sugar, and cinnamon. Mix using the kneading attachments of your mixer until you get a crumbly dough.1 ¼ cups all-purpose flour + ½ cup butter soft + ½ cup granulated sugar + 1 teaspoon cinnamon
Assemble the dish: Place the fruit mixture in a baking dish. Sprinkle the crumble on top.
Bake the apple and cherry crumble for 25-30 minutes or until golden brown.
Notes
To make the crumble by hand, use your fingers to rub the soft butter into the flour, sugar, and cinnamon until the mixture looks like coarse crumbs. Don’t overwork it - small lumps are fine.
To make the crumble in a food processor, combine the flour, sugar, cinnamon, and cold butter cut into cubes. Pulse a few times until the mixture resembles coarse crumbs. Be careful not to over-process - it should still have some small lumps for a nice texture.
Cherries: You can make the crumble with sour cherries, too. In that case, add more sugar - about 4 tablespoons - to balance the tartness.
Frozen cherries work well as well; no need to thaw them first. Just bake the crumble a little longer, about 10–15 minutes extra, to make sure the fruit is fully cooked. Keep an eye on the crumbles, they should not get too brown. If necessary, cover the dish loosely with a piece of foil.
Sweeteners: You can also mix the fruit with other sweeteners of choice, like honey, maple syrup, xylitol, or erythritol.
