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

What each ingredient does

Salt cod fish
Provides the main protein, which firms and flakes as it simmers.
Flour
Thickens the cream sauce, giving it body as the paste cooks into the liquid.
Butter
Adds richness and smooth mouthfeel, helping the flour blend into the sauce.
Milk
Forms the creamy base of the sauce and adds mild sweetness and softness.

The step that matters

Adding the flour and butter paste. If the paste is dropped in as large lumps, the flour will clump and not disperse evenly. Adding it in small pieces while simmering lets each piece hydrate and thicken the liquid smoothly.
