Ingredients to make 1 cup
- 2 tablespoons of all-purpose flour
- 2 tablespoons of butter
- 1 cup slightly warm whole milk
- salt
- pepper
- grated nutmeg
- 1 or 2 egg yolks
Preparation
In a saucepan, melt the butter on low heat. As soon as it starts to bubble (not brown) add the flour and stir with a wooden spoon until there are no lumps, Add the milk slowly, stirring constantly with a whisk, until the sauce begins to thicken - creamy without being too thick (it will thicken further after removing from the heat). Remove from the heat and stir in salt, pepper, and nutmeg. Allow the sauce to cool for a few minutes before stirring in the egg yolk until well blended.
