Why it works: Lemon and parsley 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 Spanish Mackerel
Ingredients
Directions
Prepare the fish
Split the fish down the back and remove the backbone.
Wash the fish in cold water and dry it with a clean cloth.
Sprinkle the fish lightly with coarse sea salt.
Grill and serve
Lay the fish on a buttered grill with the flesh side down over a clear fire until it begins to brown.
Turn the fish to cook the other side.
Mix together the melted butter, lemon juice, salt, and black pepper.
Serve the fish hot on a warm dish, pouring the mixture over it.
For the sauce, beat together the melted butter, lemon juice, chopped parsley, and white pepper until well combined.
Serve the sauce hot alongside the fish.

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 into flaky, tender flesh over the fire.
- Butter
- Adds richness and moisture, carrying flavour and helping the fish brown lightly on the grill.
- Lemon juice
- Adds acidity that brightens the rich butter and balances the fish's flavour.
The step that matters
Grilling the flesh side down. Starting flesh side down over a clear, steady fire lets the flesh set and brown before turning. Too hot a fire or turning too early can scorch the skin or tear the flesh apart.
Swap the white pepper
How well each one fits the dish's main ingredients (spanish mackerel, butter, lemon, pepper, sauce, parsley):
- Tarragonfits better
- Thymefits better
- Capersfits better
