A More Economical Method of Making a Pint of White Sauce

Ingredients

Directions

Make the sauce base

  1. Combine broth, milk, onion, and mace in a saucepan.

  2. Bring the mixture to a boil for 10 minutes.

  3. Mix flour and butter in a bowl until well combined.

  4. Add the flour‑butter mixture to the saucepan and stir until it boils.

  5. Reduce heat and stir occasionally until smooth.

  6. Strain the sauce through a sieve into a basin.

Finish the sauce

  1. Return the sauce to the saucepan, season with salt and lemon juice.

  2. Beat the egg yolks with 3 tablespoons of milk and strain into the sauce.

  3. Stir the sauce well.

  4. Keep the sauce warm without boiling to prevent curdling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour
Thickens the liquid into a smooth sauce when cooked with butter and heated.
Butter
Adds richness and carries the flour so it blends smoothly into the liquid.
Egg yolks
Enrich and thicken the sauce when stirred in, adding body and richness.
Milk
Forms the creamy liquid base that the flour thickens.

The step that matters

Keep the sauce warm without boiling. Once the egg yolks are added, boiling can scramble them and cause curdling. Gentle warmth thickens the sauce smoothly while keeping it silky.

Swap the mace

How well each one fits the dish's main ingredients (milk, onion, flour, butter, lemon, egg):

  1. Parsleyfits better
  2. Capersfits better
  3. Nutmegfits better
  4. Macethe original

Fit is the average pairing score against milk, onion, flour, butter, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
