1. Preheat the Oven:

• Preheat your oven to 392°F (200°C).
• Lightly grease two small ramekins or a medium-sized baking dish with butter. Set them aside.

2. Prepare the Fruit Filling:

• Wash the gooseberries, halve them, and remove any stems.
• Dice the apple into small, evenly sized cubes to ensure even cooking.
• In a large bowl, gently toss together the gooseberries, apple, raspberries, brown sugar, and a pinch of cinnamon. Set aside to allow the flavors to meld.

3. Prepare the Crumble Topping:

• In a food processor, pulse the almonds until they are ground into a coarse meal. Alternatively, you can chop them finely by hand.
• In a separate bowl, combine the ground almonds, rolled oats, flour, brown sugar, and cinnamon.
• Slowly add the yogurt to the dry ingredients, mixing with a fork until the mixture forms coarse crumbs. If the crumble seems too dry, you can add a bit more yogurt or a tablespoon of melted butter to get the right texture.

4. Assemble the Crumble:

• Divide the fruit filling evenly between your prepared ramekins or baking dish.
• Sprinkle the crumble mixture generously over the fruit, ensuring it covers the filling completely.

5. Bake:

• Place the ramekins or baking dish in the preheated oven.
• Bake for 15–20 minutes, or until the crumble topping turns golden brown and crisp.
• The fruit should be bubbly, and the top should have a nice, toasted texture.

6. Cool and Serve:

• Let the crumbles cool for about 5 minutes before serving. This allows the filling to set slightly while still being warm and comforting.
• Serve as is, or pair with a dollop of vanilla ice cream or a spoonful of crème fraîche.
