Peel, quarter and core the apples. Cut the fruit flesh smaller. Season with lemon juice, vanilla sugar and aniseed. Steam for about 10 minutes, then puree and let cool.
Defrost some raspberries one by one. Heat the remaining berries briefly and pass through a sieve. Whip cream and sugar until stiff. Fold the cream into the cooled down puree and fill into a piping bag with a large star-shaped spout.
Pour into dessert glasses and chill. Decorate with raspberries and apple wedges. Serve with the sauce.
