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 ↓
Mushroom Sauce
Ingredients
Directions
Prepare the mushrooms
Wash the mushrooms and remove the stems and outer skins.
Select mushrooms that are dull pearl in color with pale pink undersides.
For better flavor, salt the mushrooms the night before to extract their juice.
Make the sauce
Stew the mushrooms slowly in veal gravy, milk, or cream.
Add the chopped onion and season with salt and pepper.
Roll the butter in flour and add to the sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Button mushrooms
- Provide the main body and earthy flavor of the sauce as they soften and release their juices.
- Butter
- Adds richness and fat, and with flour helps thicken the sauce.
- Flour
- Thickens the sauce when rolled in butter and stirred in.
- Veal gravy or milk or cream
- Forms the liquid base that gives the sauce its body and creaminess.
The step that matters
Adding the butter and flour. Butter rolled in flour must be stirred in gradually so the flour disperses without lumps. Its starch thickens the liquid as it heats, and adding it all at once can leave clumps or a thin, uneven sauce.
Swap the onion
How well each one fits the dish's main ingredients (mushroom, butter, veal, pepper, flour):
- Shallotfits better
- Capsicumfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against mushroom, butter, veal, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
