A Very Good and Useful White Sauce

Ingredients

Directions

Make the sauce

  1. In a stew‑pan, heat 1 quart of white sauce over medium heat, stirring continually until reduced to one-third.

  2. In a bowl, whisk 2 egg yolks, then gradually add the reduced sauce while stirring.

  3. Return the mixture to the stew‑pan and bring to a boil for a few minutes.

  4. Add 1 pint of boiling milk to achieve the desired thickness, which should coat the back of a spoon.

Strain and store

  1. Strain the sauce through a fine sieve into a bowl and stir occasionally until cool.

  2. If not using immediately, store in a covered container in the refrigerator for up to 2‑3 weeks in winter or 1 week in summer.

What each ingredient does

Egg yolks
Add richness and help thicken the sauce as they set with gentle heat.
White sauce
Forms the base of the sauce, and reducing it concentrates its body and flavour.
Milk
Adds liquid to loosen the sauce and bring it to the desired thickness.

The step that matters

Returning the egg yolk mixture to the pan. Egg yolks thicken by gentle heat but can scramble if the sauce gets too hot too fast. Keep the heat moderate and stir constantly so the sauce thickens smoothly.
