Crumble the cookies very coarsely and leave them aside.
Squeeze half a lemon and mix it well with sugar (remove the seeds!).
Clean the mango and put in a mixer and whip until it is smooth and creamy. Then mix the mango puree with sweetened lemon juice and ginger and put apart.
Whip the cream with the whisk of a food processor.
Gently mix the whipped cream with the mango puree with a dipper.
Compose the cups in layers starting with a teaspoon of the creamy mixture on the bottom of the cups and continue with a layer of cookies, then back to the mango cream, until you get to level (two or three layers are ideal).
Place in the refrigerator and wait at least 30 minutes before serving with slivered almonds to decorate.
