Step 1

Place raspberries and sugar in a saucepan over very low heat for 5 minutes until the juices start to flow, then leave to cool.

Step 2

Transfer to a food processor and puree until smooth. Pass through a sieve, discarding the solids. Place strawberries in a bowl with the puree, cream, yoghurt and the meringue.

Step 3

Fold everything together until just combined, then spoon into four glasses and serve immediately.
