You can use as much fruit as you like for this recipe.  Why not try combinations of acidic and sweet fruit to get your taste buds going?!

Equipment:
1 saucepan
1 cooking hob
1 oven
1 mixing bowl
1 spoon
Your hands
1 ovenproof dish

Ingredients:
Tin of custard powder
Stewed fruit
8oz plain flour
4oz margarine
4oz sugar

To stew the fruit:
Peel the fruit if necessary.
For apples and pears chop into small pieces.  Berries don't need chopping.
Boil water in a saucepan and add the fruit.
For best results begin with only enough water to cover the fruit and add more if as necessary to avoid the fruit burning.
Stew the fruit until it is soft and add a little sugar to taste.

To make the crumble topping:
Mix together the flour and the margarine with your fingers in a large bowl until the margarine is broken up and, uhm, crumbly.
Add the remainder of the sugar to the flour-margarine mix and stir in with a spoon.

Preheat the oven to 160 degrees C.

Spread the stewed fruit evenly around the bottom of the oven dish.
Spread the crumble topping over the fruit.

Place in the oven and cook for half an hour

To make the custard:
Follow the instructions on the tin...!
