White Melted Butter

Ingredients

Directions

  1. Thicken the milk with less than 2 tablespoons of flour or a little arrowroot.

  2. Bring the mixture to a boil.

  3. Gradually stir in the small pieces of fresh butter until completely dissolved. Continue stirring to prevent the sauce from becoming oily.

  4. For a variation, use thin cream instead of milk and add lemon rind, salt, and pounded mace.

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

What each ingredient does

Flour
Thickens the milk so the butter sauce becomes smooth and coats a spoon.
Fresh butter
Adds richness and fat, giving the sauce its flavour and silky body.
New milk
Forms the liquid base that the flour or arrowroot thickens.

The step that matters

Stirring while adding the butter. Butter added in pieces must be stirred in steadily so it emulsifies into the thickened milk; if stirring stops, the fat can separate and the sauce turns oily.

Swap the mace

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

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

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