To make the cream reduced to 70%, boil 1 liter of cream.

When the liquid has decreased dramatically, weigh it, it must be about 300 g to obtain a "reduced to 70%"

Mix the reduced cream with Parmesan, ricotta.

Once the mixture is cold, add the egg whites and beat to make it homogeneous

Grease some baking cups and pour the mixture.

Bake in a bain-marie (place the cups in a pan with a couple of centimeters of water)

Remove from the mold and serve hot.
