Easy apple and rhubarb crumble

Preheat oven to 180°C (gas mark 4). Peel, slice and remove the cores from the apples and place into an ovenproof dish that is at least 3 inch deep.

Pour the contents of the canned rhubarb into the dish with the apples and mix together. Add the sugar.

To make the crumble, mix the butter with the flour in a dry bowl using your hands until you have a texture like breadcrumbs.

Add the oats and the remaining sugar and mix together.

Evenly spread the crumble mixture over the apple and rhubarb. Place  in the middle of a pre-heated oven for 30-40 mins. When the crumble is cooked, leave it to cool for at least 15 minutes. Any crumble left over can be covered with tin foil and be kept in the fridge for a couple of days.
