Apple Crumble

Grate half of an apple on a fine grater and heat it in a skillet with one portion of sugar until it forms a caramel.

Dice the remaining apples into small cubes.

Add the apple cubes, cranberries, cinnamon, 20 grams of butter, lemon zest, and lemon juice to the caramel, and simmer until the apples are tender.

Meanwhile, prepare the crumble topping: rub the flour, salt, and sugar together with the cold butter.

Place the filling at the bottom of a baking dish and sprinkle the crumble evenly over the top.

Bake for 12-14 minutes in a preheated oven at 200°C (400°F) until the topping is golden brown.
