Light Berry Dessert

Thaw frozen blackberries, pick over fresh ones and reserve a few for the garnish. Soak the gelatine in cold water, puree the blackberries and push through a sieve.

Mix the puree with the sugar, lemon juice and peel. Put the gelatine dripping wet into a small pan and dissolve over a low heat. Stir 1-2 tbsp of the blackberry puree into the gelatine, then stir the gelatine mixture into the rest of the puree.

Beat the egg whites and cream separately until stiff, then fold into the mousse one after the other. Put the mousse into small moulds, cover and chill overnight (for at least 4 hours).

To serve, dip the moulds briefly in hot water and turn out onto plates. Decorate the mousse with lime slices and blackberries. Chill.

Mix the lime juice smoothly with the sugar, a little water and the cornflour. Add the rest of the water and slowly bring to the boil, stirring. Allow to boil once then remove from the heat.
