Make this classic rhubarb crumble for an easy, family-friendly dessert. Use seasonal rhubarb and a handful of ingredients to make a stunning pud.
Based on 4 servings, adjust as needed.
Tip the chunks of rhubarb into a saucepan with golden caster sugar and the port, if using.
Cover and simmer on a very low heat for 15 mins, adding more sugar if you want. When soft (but still holding its shape) and sweet enough, pour the rhubarb into a medium baking dish.
Heat oven to 200C/180C fan/gas 6.
To make the topping, rub the self-raising flour and chilled butter together with your fingers until you have a soft, crumbly topping.
Now add the light brown muscovado sugar and chopped walnuts, if using. Mix together with your hands.
Scatter the topping over the rhubarb and bake for 30 mins or until golden brown on top.
Serve piping hot with a big jug of thick vanilla custard.
