Wash the gooseberries, clean them and cut them in halves. Marinate the berries with the spices for at least 5 min. to flavor. Before serving, beat the egg white with sugar and a pinch of salt until stiff and pick some chervil leaves. Now arrange some custard on a plate or in a bowl and add the berries, some spoons of egg white and the crumbles on top. Decorate with some chervil and your done.
