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
Cut off the tail and fins, remove the gills and insides, and wipe the fish clean without washing.
Split the back of the mackerel lengthwise to the bone.
Place the fish on a dish and season with salt, pepper, and oil.
Grill and serve
Grill the mackerel over a brisk fire for 6 minutes on each side and 4 minutes on the open back.
Melt the maitre d'hotel butter and place it on the back of the fish before serving.
Serve on a hot dish.
Second method
For the second method, fill the gills with a mixture of butter, minced parsley, chives, salt, and pepper.
Open the back from head to tail and fill the cut with the remaining mixture.
Wrap the fish in well-buttered paper and grill over a slow fire or in the oven.
Remove the paper when ready and squeeze lemon juice over 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 to flaky tender flesh over direct heat.
- Maitre d'hotel butter
- Melts over the hot fish, adding richness and moisture to the surface.
- Oil
- Coats the fish so the skin browns and does not stick to the grill.
- Parsley
- Adds fresh, herbal aroma to the buttery filling.
- Lemon
- Adds acidity that brightens the rich butter and oily fish.
The step that matters
Grilling over a brisk fire. Mackerel is oily and thin, so a hot fire sears the skin and sets the flesh quickly. Too low a heat dries the fish before the outside browns.
Swap the chive
How well each one fits the dish's main ingredients (pepper, butter, parsley, lemon):
- Shallotfits better
- Carrotfits better
- Spinachfits about as well
- Chivethe original
Fit is the average pairing score against pepper, butter, parsley, lemon. Candidates are from the same food group and used in at least 100 recipes.
