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 Mackerel
Ingredients
Directions
Prepare the fish
Empty the fish without washing it and wipe it well.
Slit open the back and sprinkle coarse sea salt over it.
Brush the fish with oil, lard, or dripping to prevent sticking.
Cook and serve
Broil the fish until cooked through.
In a bowl, mix dripping with chopped fennel, parsley, lemon juice, salt, and pepper.
Serve the fish on a hot dish and spread the mixture over it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mackerel
- Forms the main body of the dish, cooking through under direct heat to become flaky and tender.
- Oil, lard, or dripping
- Coats the skin to prevent sticking and helps it brown under the broiler.
- Fennel
- Adds a fresh, aromatic anise flavour to the herb mixture spread over the fish.
- Lemon juice
- Adds acidity that brightens the rich fish and the fat in the herb mixture.
The step that matters
Broil the fish until cooked through. Under a broiler the surface can scorch before the thick center sets. Watch closely and check the flesh at its thickest point, since fish is cooked when it turns opaque and flakes easily.
Swap the fennel
How well each one fits the dish's main ingredients (parsley, lemon, pepper):
- Marjoramfits better
- Thymefits better
- Dillfits better
- Fennelthe original
Fit is the average pairing score against parsley, lemon, pepper. Candidates are from the same food group and used in at least 100 recipes.
