Recipe Ingredients

Note: The full quantities are shown in the recipe card below.
- Unsalted butter - unsalted butter gives you complete control of the overall flavour of your recipe, as the salt content in different butter brands can vary greatly.
- Flour - we use plain flour (all-purpose flour), but you could also use self-raising flour.
- Brown sugar - gives the topping a lovely caramel crunch flavour.
- Rhubarb - the star of the dish!
- Caster sugar - we use a tablespoon of white sugar to toss into the rhubarb as we don't like it too tart. Add more or less, depending on taste.
How to Make Rhubarb Crumble
Note: This is a summary of the instructions. The full ingredients and instructions are shown in the recipe card below.

- Wash the rhubarb stalks and trim the ends. Cut the rhubarb stalks into 2-3cm pieces and arrange them in a shallow baking dish (there's no need to precook the rhubarb as it will soften in the oven). Sprinkle over the sugar and toss to combine. Rhubarb shrinks quite a bit, so don't be afraid to pile it high in the baking dish.

- Add the flour and butter to a large bowl. Ensure the butter is chilled so it's easy to rub together without sticking.

- Rub together with your fingertips until bread crumbs form (a few large chunks of butter are okay as they will melt in the oven. Stir in the sugar.

- Pour the topping over the rhubarb and press down lightly (not too much) with the back of a fork. Bake in the oven until golden on top, and the rhubarb starts to bubble around the edges.
Serving Suggestions
The ultimate accompaniment to a crumble is hot custard. If you're not a custard fan, whipped cream or vanilla ice cream tastes just as good.
