Wash, clean and finely dice 200 g strawberries. Mix with 1 tablespoon of sugar and leave to stand for about 20 minutes. Separate the eggs. Beat the egg whites until stiff, then pour in 1 tbsp. sugar. Beat 100 g cream until stiff.
Cream egg yolks, 50 g sugar and vanilla sugar. Stir in yoghurt. Fold in berries, cream and beaten egg white. Cover and freeze overnight, e.g. in an empty ice cream container.
Allow ice to thaw a little before moulding. Wash the remaining strawberries and put 4 aside. Clean the rest and cut into small pieces. Mix with 2 tablespoons of sugar. Chop the chocolate and melt in a hot water bath. Dip the whole strawberries halfway into the chocolate and let them dry on baking paper.
Stir butter and 100 g cream into the remaining chocolate and warm up.
Form 4 large balls from half the ice cream mass (refreeze the rest). Arrange and decorate with strawberries and chocolate sauce.
