White Sauce and Cream Sauce

Ingredients

Directions

Make the sauce

  1. In a thick saucepan, melt the butter over medium heat and stir in the flour until well blended.

  2. Gradually add the boiling water, half a cup at a time, stirring smoothly after each addition to avoid lumps.

  3. Once all the water is added, season with salt, white pepper, and nutmeg, then let it boil for a moment.

Variations

  1. For a richer sauce, replace half the water with milk; for cream sauce, use all milk.

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

What each ingredient does

Butter
Carries the flour and adds richness and flavour to the sauce.
Flour
Thickens the sauce as its starch swells in the hot liquid.
Boiling water
Forms the liquid base that the flour thickens into a sauce.

The step that matters

Adding the liquid gradually. Flour starch clumps when liquid is poured in all at once. Adding the liquid a little at a time while stirring keeps the starch dispersed, so the sauce stays smooth and lump-free.

Swap the white pepper

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

  1. Cinnamonfits better
  2. Cardamomfits better
  3. Allspicefits better
  4. White pepperthe original

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