Step 1

Preheat the oven to 200°C/fan180°C/ gas To prepare the filling, mix the frozen fruits, apple chunks, caster sugar, orange zest and cornflour together in a large bowl then spoon into a 1.8-litre ovenproof dish.

Step 2

For the cobbler crumble, put the flour, ground almonds and 70g of the sugar in a food processor, add the butter and pulse until it resembles fine breadcrumbs. Add the buttermilk and pulse again to form a soft dough.

Step 3

Place large spoonfuls of the cobbler crumble mixture haphazardly over the filling, then sprinkle with the flaked almonds and remaining sugar.

Step 4

Bake for 35-40 minutes until bubbling and golden brown. Serve with a jug of pouring cream.
