Why it works: Lemon and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 14,036 recipes mention both. 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
- Bream
- Forms the main flaky fillets that are marinated and then fried.
- Lemon juice
- Acidity brightens the fish and begins to flavour it during marinating.
- Onion
- Adds aromatic flavour that infuses the fish during the one-hour marinade.
- Tomato sauce
- Provides acidity and moisture to accompany the crisp fried fillets.
The step that matters
Frying the fillets until golden. Batter or flour must be fried at a steady, hot temperature so the coating crisps and browns before the delicate fish overcooks and becomes dry.

Fit is the average pairing score against lemon, parsley, tomato, sauce, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
