Why it works: Mushroom and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 12,525 recipes. Both carry trans-2-decenal, which smells waxy, orange. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Provide the main flavour and soft, tender body of the sauce.
- Velouté or rich sauce
- Forms the base of the sauce and gives it body and richness.
- Butter
- Adds richness and a smooth mouthfeel to the sauce.
- Flour
- Works with the butter to thicken the sauce.
The step that matters
Rub the butter with the flour and stir into the mixture. Flour and butter must be blended smoothly so they disperse evenly. Lumps of flour left unmixed will not thicken the sauce properly and may stay as pasty specks.
Swap the mace
How well each one fits the dish's main ingredients (mushroom, sauce, pepper, butter, flour):
- Capersfits better
- Parsleyfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against mushroom, sauce, pepper, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
