You’ll need a deep dish pie plate or six large ramekins. Butter lightly.
Place the stoned peach eighths and the quartered strawberries into the pie dish or the ramekins, whichever you’re using, add the sugar and gently mix together.
Place the flour and the sugar in a bowl. Rub in the cubes of butter, but not completely — the mixture should still be nice and coarse. Scatter the crumble topping over the fruit and refrigerate the prepared crumble until you need to cook it.
Bake 30-40 minutes until peaches are tender , 15-20 for ramekins.
