Soak gelatine in cold water. Separate eggs. Cream egg yolks, sugar and vanillin sugar. Add sherry and stir in. Squeeze the gelatine and dissolve over low heat, allow to cool slightly. Then stir into the cream and chill.
Whip egg whites and cream separately until stiff. When the cream starts to get firm, fold in first the cream, then the beaten egg white. Chill the cream for another 2 hours. Finely chop the pistachios. Serve the cream garnished with the pistachios. Amaretti biscuits taste good with it
Preparation time approx. 30 minutes (without waiting time)
