rhubarb and apple crumble

The easiest and tastiest crumble I've made yet. Crunchy topping and not too tart!

Cooked in a 7inch long baking tin and will feed four

Ingredients

7/8  sticks of rhubarb
110g/4oz demerara sugar
110g/4oz softened butter
200g/7oz plain flour
8 tablespoons water
4 tablespoons castor sugar (to cook with the rhubarb)

To Cook

Oven preheated to 180 degrees centigrade/gas 4/350f

Chop the rhubarb into small pieces and put onto a baking tray with the water and castor sugar, bake in the oven for 10 minutes or so.
When done add this to a baking tin, I used a 7 inch long tin. Make sure it's deep.

Add the flour, demerara sugar and butter to either a bowl and rub together with your fingers or add to a food processor and combine until breadcrumb like mixture is made.

Put this mixture over the top of the rhubarb and put in the oven for 45 minutes to bake.

Eat with custard, cream or entirely on its own.
