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

What each ingredient does

Macaroni: Forms the bulk of the dish and gives it its body and chewy bite.
Milk: Forms the liquid base of the sauce, carrying the flour and cheese smoothly.
Butter: Adds richness and fat, helping the flour form a smooth roux with the milk.
Flour: Thickens the milk into a smooth sauce as it cooks with the butter.
Cheese: Melts into the sauce to add savoury flavour and a creamy, stretchy texture.

The step that matters

Stirring the butter‑flour mixture into the boiling milk. Adding the roux to boiling liquid all at once can leave lumps, because starch granules clump before they disperse. Stir constantly while adding it gradually so the flour hydrates evenly and the sauce thickens smoothly.
