Why it works: Pepper and lemon 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 ↓

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
- Forms the main body of the dish and carries the flavour of the herbs and sauce.
- Butter
- Adds fat and richness to the herb sauce, carrying flavour and giving a smooth texture.
- Cream
- Adds richness and a smoother, silkier texture to the pan sauce.
- Flour
- Light coating on the fish that helps the surface hold on to the sauce.
- Herbs
- Provide aroma and fresh flavour to the stock and butter sauce.
The step that matters
Simmer gently for 10 minutes. Boiling vigorously can break up the delicate fish and toughen its protein, so a gentle simmer keeps the mackerel moist and intact while it cooks through.

Fit is the average pairing score against butter, flour, pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
