Heat milk and cream in saucepan until it simmers and turn off heat.

Slowly whip in cheese, then remove pan from heat entirely.

Put egg yolks in mixing bowl and slowly whip in a little of the milk/cream mix at a time until mixed completely.

Place back on low heat and stir regularly until it simmers again.

Once it begins simmering, remove from heat again so that it thickens.

(Optional): add salt/pepper to taste.
