Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Broiled Trouts, with 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
Gut and wash the trouts thoroughly.
Cook
In a pan, melt the butter and add parsley, green onions, sweet herbs, pepper, salt, and anchovy.
Place the trouts in the pan and cook over hot cinders, turning occasionally.
Transfer the pan to the oven at 400°F (200°C) to brown the fish.
Serve
Once cooked, dish up the trouts and drizzle with lemon juice.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Trout
- Forms the main body of the dish, cooking to a tender, flaky texture.
- Anchovy
- Adds savory depth and umami to the butter and herb mixture.
- Butter
- Carries the herbs and seasonings and adds richness and moisture to the fish.
- Green onions
- Contribute a mild, fresh onion aroma to the herb butter.
The step that matters
Turning the trout over hot cinders. Fish is delicate and can dry out or stick if overcooked or left unturned, so turning occasionally helps it cook evenly and brown without drying.
Swap the onion
How well each one fits the dish's main ingredients (butter, parsley, pepper, anchovy, lemon):
- Shallotfits better
- Spinachfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against butter, parsley, pepper, anchovy, lemon. Candidates are from the same food group and used in at least 100 recipes.
