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

What each ingredient does

Mutton
Provides the meat that becomes tender in the simmering sauce.
All-purpose flour
Dusted on the mutton, it helps thicken the sauce as it simmers.
Butter
Adds richness and carries the flavour of the softened onion.
Onion
Softens while cooking, adding sweetness and savoury depth to the sauce.
Beef gravy stock or glaze
Supplies the liquid and beefy flavour that forms the sauce.

The step that matters

Simmering the mutton until the sauce thickens. Flour on the meat thickens the liquid only when it is simmered gently long enough to swell the starch. Boiling hard or stopping too early can leave the sauce thin or lumpy.

Swap the onion
