Why it works: Mushroom and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 13,580 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Very small flaps of mushrooms
- Provide the main body and earthy flavor of the sauce as they soften in the gravy.
- Rich brown gravy
- Forms the liquid base that carries the flavor and gives the sauce its body.
- Thickening (such as cornstarch or flour)
- Starch granules swell when heated, thickening the gravy to the desired consistency.
- Mushroom ketchup
- Adds concentrated savory, umami depth to finish the sauce.
The step that matters
Add thickening to achieve desired consistency. Starch needs to be heated in the liquid to swell and thicken it. Adding too much at once can make the sauce lumpy or gluey, so add it gradually and let it simmer until the sauce reaches the desired thickness.
Swap the mace
How well each one fits the dish's main ingredients (mushroom, pepper, flour, ketchup):
- Marjoramfits better
- Thymefits better
- Turmericfits better
- Macethe original
Fit is the average pairing score against mushroom, pepper, flour, ketchup. Candidates are from the same food group and used in at least 100 recipes.
