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

What each ingredient does

Flour
Cooked in butter to form a roux that thickens the sauce.
Butter
Carries the browning of the vegetables and forms the roux with flour.
Mushrooms
Add savoury, earthy depth and body to the sauce as they cook down.
Tomato sauce
Adds acidity, colour and savoury depth to the finished sauce.
Stock
Provides the liquid that the roux thickens into a sauce.

The step that matters

Melt the butter and flour until pale brown. Cooking the roux long enough cooks out the raw flour taste and thickens well, but over-browning weakens its thickening power and darkens the sauce. Stir steadily over moderate heat so it does not scorch.

Swap the tomato

How well each one fits the dish's main ingredients (mushroom, carrot, onion, shallot, butter, flour, sauce):

Fit is the average pairing score against mushroom, carrot, onion, shallot, butter, flour, sauce. Candidates are from the same food group and used in at least 100 recipes.
