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

What each ingredient does

Fresh butter
Melts into the sauce to add richness and a smooth, glossy body.
Mushroom ketchup
Adds deep savoury, umami flavour that gives the sauce its character.
Lemon juice
Adds acidity that brightens the rich butter and gravy.
Loaf sugar
Balances the sharpness of the lemon and mustard with a touch of sweetness.

The step that matters

Heat gently while stirring. Butter can separate or scorch if the heat is too high, so warming slowly while stirring keeps the emulsion smooth and the sauce from tasting burnt.

Swap the mustard

How well each one fits the dish's main ingredients (sugar, lemon, butter, mushroom, ketchup, pepper):

Fit is the average pairing score against sugar, lemon, butter, mushroom, ketchup, pepper. Candidates are from the same food group and used in at least 100 recipes.
