I love any fruit crumble and I love rhubarb, so this recipe was a must. The crumble topping is a little different from what I am used to, but works well. The ground cassia is not an essential ingredient but does add a nice spice to the mix.
Because the rhubarb will collapse in the middle when taken out of the oven, it is important to have it well covered with crumble.
8 stalks rhubarb
4 granny smith apples
50g unsalted butter
2 tablespoons caster sugar
360g plain flour
1 teaspoon baking powder
1 teaspoon ground cassia
180g caster sugar
250g chilled unsalted butter
1 teaspoon vanilla bean
To make the crumble, sift the flour, baking powder and ground cassia into a bowl and add the caster sugar. Dice the butter, then rub it and the vanilla extract into the flour using your fingertips until the mixture is crumbly and lumpy.
Wash the rhubarb, discard the leaves and chop the stalks into 3cm lengths. Core, peel and cut the apple into similar sized chunks.
Butter a medium-sized baking dish with most of the softened butter, leaving a little to dot over the fruit. Mix the rhubarb and apple into the dish, then dot with the remaining butter and sprinkle with the caster sugar.
Preheat the oven to 200C. Generously pile the crumble over the fruit. Bake for 45 – 60 minutes, or until the crumble is golden brown and the juice from the fruit is bubbling around the edges.
Serve with thick cream.
