I made this with:
- 3 sticks of rhubarb (cut into 3cm lengths)
- 3 cox’s apples (peeled, cored and thickly sliced)
- 2 tbsp water
- 2 tsp castor sugar
- 500g frozen raspberries (£2.29 from Lidl) defrosted
Put the rhubarb and apples in a microwavable dish. Add the water and sugar. Cover, and cook at 750W for 3 minutes. Stir and cook for another 2 minutes (at 750W).
Add the raspberries, stir in, and cook (at 750W) for 4 minutes. Stir and cook for further 2 minutes (at 750W). Cooking time will be longer if you leave the rhubarb and apple mixture to cool before adding the raspberries (or add the raspberries while still partly frozen).
Leave to cool and store in the fridge. Makes about 1 litre of compote.
