Instructions
-
Heat the oven to 190°C. Peel and core the apples, then cut them into 2 cm chunks.
~10 min
Cutting apples into even 2 cm chunks ensures they cook at the same rate and become tender without turning to mush.
Dicing Cut apples into uniform 2 cm chunks so they cook evenly. A sharp knife and steady, guided cuts prevent bruising and ensure consistent size.
-
Spread the apple chunks and blackberries in the baking dish. Sprinkle 40 g of the sugar and the pinch of salt over the fruit and toss gently to coat.
~3 min
Sugar draws out the fruit's juices through osmosis, creating a syrupy filling that bubbles and thickens as it bakes.
If your apples are very tart, taste a raw slice first and add up to 20 g more sugar to the fruit.
-
Put the flour and the remaining 70 g sugar in the mixing bowl. Add the butter cut into 1 cm cubes and rub it in with your fingertips or a pastry cutter until the mixture looks like coarse damp crumbs with no dry flour left.
~5 min
Rubbing cold butter into flour coats the flour particles with fat, which limits gluten development and produces a crumbly, crisp topping.
Cold butter straight from the fridge gives the crumbliest topping: warm butter rubs into a paste and bakes into a flat, hard lid.
Creaming butter Rub cold butter into flour until it looks like coarse damp crumbs with no dry flour. Stop before it becomes a paste; overworking makes a hard topping.
-
Scatter the crumble over the fruit in an even layer, leaving a few gaps so steam can escape. Do not press it down.
~2 min
Leaving gaps allows steam to escape so the topping stays crisp instead of becoming soggy from trapped moisture.
-
Bake on the middle rack until the topping is golden brown and the fruit juices bubble up around the edges, 35 to 40 minutes. If the top browns before the fruit is tender, cover loosely with foil.
~40 min
Baking on the middle rack gives even heat from top and bottom, so the topping browns while the fruit becomes tender.
-
Let the crumble stand for 10 minutes so the juices settle and the topping firms up before serving.
~10 min
Resting allows the hot juices to thicken and redistribute, so the filling sets and the topping firms up for cleaner serving.
