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

What each ingredient does

Flour: Thickens the milk and butter into a gravy as it simmers.
Butter: Adds richness and fat that carries the curry flavour.
Milk: Forms the creamy base of the gravy and adds body.

The step that matters

Letting the gravy simmer until it thickens. Flour needs to simmer in the liquid for its starch to swell and thicken the sauce. Stopping early leaves the gravy thin and floury tasting, while stirring less or heating too hard can cause lumps or scorching on the bottom of the pot.
