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
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Remove the gills from the mushrooms, leaving the stalks on, and wash them well.
Place the mushrooms upside down on a sieve to drain.
Cook
In a saucepan, melt the butter with the chopped parsley and onion over medium heat for 1 minute.
Arrange the mushrooms stalk-side up on a baking pan and pour the butter mixture over them.
Season with coarse sea salt and black pepper, then broil in the oven at 400 °F (200 °C) until done.
Finish
Add the stock to the mushrooms and bring to a boil.
Serve hot, pouring the cooking liquid over the mushrooms.
An hour and a quarter before serving, add the red wine to the cooking liquid.

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 into tender, juicy caps as they cook.
- Butter
- Adds richness and fat, carrying flavour and helping the mushroom surfaces brown under heat.
- Onion
- Contributes savoury aroma and sweetness as it softens in the melted butter.
- Red wine
- Adds acidity and depth, deepening the colour and flavour of the cooking liquid.
- Stock
- Supplies moisture and savoury body to the liquid that surrounds the mushrooms.
The step that matters
Broiling until done. Under a broiler the surface heats fast, so mushrooms can dry out or scorch before the centres soften. Watching closely keeps them moist and evenly cooked.
Swap the onion
How well each one fits the dish's main ingredients (mushroom, butter, parsley, pepper, red wine):
- Shallotfits better
- Carrotfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against mushroom, butter, parsley, pepper, red wine. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
