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

What each ingredient does

Mustard
Helps bind the oil and vinegar into a smooth mixture and adds sharp flavour.
Salad oil
Adds richness and a smooth, silky body to the sauce.
Vinegar
Adds acidity that sharpens and balances the fat.
Butter
Adds richness and a rounded flavour when cooked with the onion.
Flour
Thickens the liquid into a smooth sauce as it cooks with the gravy.
Onion
Adds savoury sweetness and aroma once lightly coloured in butter.

The step that matters

Gradually mix in the gravy from the bones. Flour forms a stiff paste that clumps when liquid is poured in all at once. Adding the gravy slowly and stirring lets the starch disperse evenly, giving a smooth, thickened sauce.

Swap the onion
