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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Perch
- Provides the main protein that firms and turns flaky when fried.
- Flour (in the method)
- Forms a thin coating that browns in the hot oil and crisps the surface.
- Lemon juice
- Adds acidity that brightens the flavour of the marinated fish.
The step that matters
Frying until golden brown. Fish cooks quickly, so overheating or overcooking can dry out the flesh. The flour coating needs enough hot oil to brown and crisp, while the fish is cooked through only when it turns firm.
Swap the onion
How well each one fits the dish's main ingredients (parsley, lemon):

- Onionthe original
Fit is the average pairing score against parsley, lemon. Candidates are from the same food group and used in at least 100 recipes.
