White Sauce

Ingredients

Directions

Prepare the milk

  1. In a stew-pan, combine the milk, onion, bay leaf, and peppercorns; bring to a boil.

Make the sauce

  1. In a separate bowl, mix the flour with the butter until smooth.

  2. Add the flour mixture to the stew-pan and stir over heat for a few minutes.

  3. Pour in the white stock or water and stir until it boils.

  4. Gradually stir in the boiling milk mixture, season with salt and nutmeg, and simmer for 15 minutes.

  5. Skim the sauce and strain it through a fine strainer or cloth.

Finish

  1. For a richer sauce, stir in a small piece of fresh butter or a little cream after straining, but do not allow it to boil again.

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 as it cooks with the butter.
Butter
Forms a roux with the flour and adds richness and smooth mouthfeel.
Milk
Forms the main liquid of the sauce, giving body and creamy flavour.

The step that matters

Adding the boiling milk gradually. Stirring hot liquid into the roux a little at a time keeps the starch dispersed, so the sauce thickens smoothly without lumps.

Swap the onion

How well each one fits the dish's main ingredients (milk, clove, flour, butter, nutmeg):

  1. Arrowrootfits better
  2. Shallotfits better
  3. Leekfits better
  4. Onionthe original

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