In a bowl, whisk sugar with the egg yolks until thick, foamy and pale.
Pour the mascarpone into the mixture and starting with a fork, whisk until all lumps are completely melted.
Add egg white heavy whipped, and gently pour it into the mascarpone cream.
Keep in refrigerator for at least 1 hour.
Serve the cream with some strawberries cut into the bottom of the cup and some whole ones on top, and if you like with some dark chocolate cut into irregular pieces.
