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
Ingredients
Directions
Make the gravy
Wash the mushrooms thoroughly and place them in a saucepan.
Add the veal gravy or white broth, pepper, salt, and nutmeg.
Simmer until the mushrooms are tender.
Thicken and finish
In a separate bowl, mix the butter with flour or arrowroot to form a paste.
Add the paste to the saucepan to thicken the sauce and simmer for a few more minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Provide the main body and earthy flavour of the sauce as they soften and release their juices.
- Butter
- Adds richness and fat, and combines with flour to form a paste that helps thicken the sauce.
- Flour or arrowroot
- Thickens the sauce by absorbing liquid and swelling when heated, giving it body.
- Veal gravy or white broth
- Forms the liquid base of the sauce, carrying flavour and setting the overall volume.
The step that matters
Adding the butter and flour paste. If the paste is added without being blended smoothly, or the sauce is not simmered after, lumps can form and the starch may stay raw and taste floury. Simmering gelatinises the starch so the sauce thickens evenly.
Swap the nutmeg
How well each one fits the dish's main ingredients (mushroom, veal, pepper, butter, flour):
- Thymefits better
- Parsleyfits better
- Marjoramfits about as well
- Nutmegthe original
Fit is the average pairing score against mushroom, veal, pepper, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
