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

What each ingredient does

Butter
Adds richness and fat, giving the sauce its smooth, rounded flavour.
Flour
Thickens the butter and water mixture into a smooth sauce.
Lemon juice
Adds acidity that brightens the buttery sauce and balances its richness.

The step that matters

Stirring the flour and butter before adding the water. Flour must be cooked briefly in the melted butter and mixed well so it dissolves evenly; otherwise the sauce can turn lumpy when the liquid is added.

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

  1. Shallotfits better
  2. Arrowrootfits better
