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

What each ingredient does

Flour
Thickens the sauce as its starch swells and sets when heated.
Butter
Adds fat for a smoother, richer mouthfeel and a glossy finish.
Vinegar
Adds sharp acidity that gives the sauce its tang.
Water
Forms the liquid base that the flour thickens.
Lemon extract
Adds a citrus aroma and flavor in a small amount.

The step that matters

Boil while stirring constantly until the flour is cooked. Flour lumps easily if it is not kept moving in the hot liquid. Its starch must reach a boil to thicken fully and lose its raw, pasty taste, so the sauce is cooked through only when it has boiled and the flour no longer tastes raw.

Swap the lemon

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

  4. Lemonthe original

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