Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Fillets of Mackerel Stewed in Wine
Ingredients
Directions
Prepare the fish
Remove the flesh from the bones of the mackerel and cut it into six equal parts if large, or leave whole if small.
Stew the fish
Melt the butter in a pan.
Add the flour and cook for one minute.
Add the cayenne, salt, lemon rind, and the fillets of fish.
Cook gently for 4 to 5 minutes, turning once.
Pour in the port wine, Harvey's sauce, soy sauce, and lemon juice, and stew until the thinner parts of the fish begin to break.
Carefully lift the fillets out and place them on a dish.
Serve
Stir the mustard into the sauce before serving.
Serve hot with the sauce.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mackerel fillets
- Provides the main protein, which firms as it cooks and flakes when done.
- Butter
- Carries the flavour of the dish and gives the sauce richness.
- Flour
- Thickens the sauce slightly once it is cooked with the butter.
- Port wine
- Forms the liquid of the stew and adds sweetness and depth of flavour.
- Lemon rind
- Adds bright aromatic oils that lift the richness of the fish and butter.
The step that matters
Stewing until the thinner parts begin to break. Thin pieces of fish cook through quickly and turn dry or fall apart if left too long, while thick pieces stay underdone. Watching the thinner parts keeps the fillets tender and intact.
Swap the mace
How well each one fits the dish's main ingredients (butter, flour, lemon, pepper, port wine, sauce, mustard):
- Capersfits better
- Tarragonfits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against butter, flour, lemon, pepper, port wine, sauce, mustard. Candidates are from the same food group and used in at least 100 recipes.
