Defrost and drain the strawberries.
Put the juice in a measuring cup and add enough cold water to make 1 cup of liquid.
Soften the gelatine in this liquid for 5 mins.
Add 1 cup of boiling water and stir until the gelatine is dissolved.
Add the strawberries.
Cool the mixture for 30 minutes or until it is slightly thickened.
Meanwhile, whip the cream until slightly thickened.
Add the sugar gradually, beating constantly, until the cream is thick.
Fold the whipped cream into the strawberry and gelatine mixture.
Pour into a fancy mould.
Chill in the refrigerator for 2 hours or until firm.
