Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Ingredients
Directions

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Main ingredient that softens and browns in the hot butter, becoming tender and savoury.
- Butter
- Conducts heat to the mushrooms and adds fat for browning and a rich flavour.
The step that matters
Placing the mushrooms gill side down in hot butter. Starting gill side down lets the cap-side moisture escape gradually while the gills contact the hot fat and brown. Hot butter sears the surface quickly, so the mushrooms cook rather than steam.
Swap the lemon
The recipe marks lemon as optional. How well each one fits the dish's main ingredients (mushroom, butter, pepper):
- Lemonthe original
- Plumfits about as well
- Mangofits less well
- Cherryfits less well
Fit is the average pairing score against mushroom, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
