Chilled mandarin and lemon mousse

Put the fruit in a bowl. Measure the fruit juice-it should be no more then 250ml. Pour the measured juice into a small saucepan and sprinkle with gelatin. Leave to soak for 5 minutes then heat gently without boiling until the gelatin has dissolved, leave to cool.

Add the egg yolks and sugar to the fruit zest and whisk until the mixture is thick and creamy. With clean beaters, whisk the egg whites in a clean bowl until stiff and whip the cream in another bowl until it forms soft peaks.

Gently whisk the gelatin mixture into the yolks, then fold in the cream and finally the egg whites. Spoon the mixture into glasses and chill for 3-4 hours until set. Decorate with whipped cream and lemon and mandarin zest. Then serve.
