Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Broiled Mushrooms
Ingredients
Directions
Prepare
Pare the mushrooms, leaving the stalks on and pointed.
Wash them well and let them drain.
Make the butter mixture
In a saucepan, melt the butter.
Add the parsley and onions to the melted butter and fry the mixture for 1 minute.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Form the main body of the dish and soften and release their moisture as they broil.
- Butter
- Carries the flavour and coats the mushrooms, helping them brown and stay moist.
- Port or claret
- Adds wine flavour and acidity that balances the rich butter.
- Onions
- Add savoury sweetness and aroma when softened in the butter.
The step that matters
Broil the mushrooms until done. Mushrooms hold a lot of water, so under-cooked ones stay soggy while over-cooked ones shrink and dry out. Watching the surface for browning and softening gives a tender result with concentrated flavour.
Swap the onion
How well each one fits the dish's main ingredients (mushroom, butter, parsley, pepper):
- Shallotfits better
- Carrotfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against mushroom, butter, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
