Why it works: Fennel and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 625 recipes. Both carry myristicin, which smells spice, warm. The science ↓
Broiled Mackerel
Ingredients
Directions
Prepare the fish
Cut a slit in the back of the mackerel for even cooking.
Grease the bars of a grill and place the mackerel over a clear, slow fire.
Sprinkle coarse sea salt and black pepper over the fish.
Cook and serve
Cook until thoroughly done on both sides.
Transfer to a hot dish and rub butter over the fish.
Stuff the fish with chopped fennel and parsley, seasoned with salt, pepper, and a bit of butter.
Serve with fennel sauce, parsley, and butter.

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, cooked through by grilling over a slow fire.
- Butter
- Adds richness and moisture to the fish as it is rubbed on and used in the stuffing.
- Fennel
- Adds a light aniseed aroma to the stuffing and the sauce.
The step that matters
Cook until thoroughly done on both sides. Mackerel is an oily fish that can dry out or stay underdone at the thick parts. Grilling over a slow, steady fire and checking both sides helps it cook evenly through without scorching the skin.
Swap the fennel
How well each one fits the dish's main ingredients (pepper, butter, parsley, sauce):
- Tarragonfits better
- Capersfits better
- Thymefits better
- Fennelthe original
Fit is the average pairing score against pepper, butter, parsley, sauce. Candidates are from the same food group and used in at least 100 recipes.
