Whip the cream until stiff. Add 1 sachet of vanilla sugar. Fold into the gelling puree. Pour the cream into 4 coldly rinsed moulds or cups (each containing approx. 150 ml) and chill for at least 4 hours.
Roast the almonds in a pan without fat, take them out. Dip the moulds briefly in hot water and turn them over onto 4 plates. Serve with rum fruits. Sprinkle with almonds and dust with icing sugar
