Our rhubarb grows like mad - this is a brilliant use of it, making a really tasty dessert.
Heat the oven to 180C
Put the rhubarb, caster sugar and water in a saucepan on the hob, bring to a simmer, cover and leave on a low heat for about 15 minutes.
Place the rhubarb in a baking dish.
Put the flour, butter and demerara sugar in a mixing bowl and rub together with your fingers to make breadcrumbs.
Sprinkle the crumble over the rhubarb in the baking dish and put in the oven of about 30 minutes until golden brown on top - you can always pop it under the grill at the end to brown it if you'd like.
Serve with vanilla ice cream or custard
