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
Cut a slit in the back of the mackerel for even cooking.
Grease a grill and place the mackerel over a clear, slow fire.
Sprinkle salt and pepper over the fish.
Cook and serve
Cook until done on both sides, then transfer to a hot dish.
Rub butter over the fish and stuff with scalded, chopped fennel and parsley, seasoned with salt and pepper.
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
- Is the main protein, cooked whole so the flesh sets and browns over the fire.
- Butter
- Adds richness and moisture, coating the fish as it cooks.
- Fennel
- Adds a mild aniseed aroma to the stuffing and sauce.
The step that matters
Cook until done on both sides. Over a slow fire, fish can dry out before the thickest part is cooked through. Cutting the slit in the back helps heat reach the centre evenly, and checking doneness on both sides prevents undercooking or drying.
Swap the fennel
How well each one fits the dish's main ingredients (pepper, butter, parsley):
- Thymefits better
- Marjoramfits better
- Tarragonfits better
- Fennelthe original
Fit is the average pairing score against pepper, butter, parsley. Candidates are from the same food group and used in at least 100 recipes.
