Why it works: Lemon and pepper 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 ↓
Mushrooms for
Ingredients
Directions
Prepare
Cut away the gritty end of the stalk and pare the mushrooms.
Place the mushrooms in a basin of cold water and wash them well.
Lift the mushrooms out of the water with both hands to leave the sediment at the bottom.
Cook and store
In a saucepan, combine the mushrooms, lemon juice, water, butter, salt, and pepper.
Shake the saucepan constantly and let it boil for 10 minutes.
Transfer to a jar, cover closely, and store.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Are the main substance, cooking down in their own moisture with the butter and water.
- Butter
- Adds fat and richness, carrying flavour and helping give the mushrooms a silky texture.
- Lemon juice
- Adds acidity that brightens the flavour and helps keep the mushrooms pale.
The step that matters
Shake the saucepan constantly while boiling. Constant movement keeps the mushrooms from sticking and scorching on the bottom of the pan and helps them cook evenly in the liquid and butter.
Swap the lemon
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.
