The recipe is really easy and here it is:-
Blackberry and Apple Crumble
3 large cooking apples
Half a pint or thereabouts of Blackberries
Grease the dish well. Peel, core and chop the apples and arrange on the base of the bowl and place the blackberries on top. Sprinkle half the sugar over the fruit, and cover with 2-3 tablespoons of water.
Now in a separate bowl rub together the flour and the butter, to make the "crumble". Place this over the fruit. Sprinkle the remaining sugar over the top, and bake in a slow-medium oven for 45 minutes, or until the "crumble" is a golden brown (Gas Mark 3-5, 180-190 C, 350-375 F). Delicious on its own, or with icecream, custard or cream.
