For 4 people.

The standard pyrex cups work best to unmold because they are wider on top and the mousselines slide easily from them.

1 cup of milk
1/3 cup of flour
4 Tbsp of butter
3 egg yolks
2 egg whites
1 cup of freshly ground parmesan cheese
1 cup of heavy cream
2 Tbsp of butter
salt and pepper

• Heat milk to warm.
• Pour it slowly into the flour and mix thoroughly.
• Whisk the mixture over medium high heat until it thickens.
• Off the heat, add 4 Tbsp of butter, one at a time, then add 1/2 cup of the parmesan cheese, three egg yolks, salt and pepper.
• Beat the 2 egg whites stiff.
• Fold into the mixture.
• Butter the molds and fill 3/4 full.
