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

What each ingredient does

Salmon
Is the main protein, cooked gently in salted water until its flakes separate.
Butter
Melts with the flour to form the fat base of the sauce, adding richness.
Flour
Cooked with butter to form a roux that thickens the sauce.

The step that matters

Stir in the boiling water gradually. Adding the liquid slowly to the hot roux lets the flour starch disperse evenly, so the sauce thickens smoothly without lumps.
