Why it works: Pepper and mustard are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 15,430 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mackerel
- The main fish, which cooks gently in the simmering sauce until flaky and tender.
- Butter
- Melted with the flour to form a smooth base that gives the sauce richness and body.
- Flour
- Mixed with the butter to thicken the sauce and give it structure.
- Claret
- Forms the liquid of the sauce, adding acidity and wine flavour as it reduces.
- Prepared mustard
- Stirred into the sauce to add sharp, pungent flavour that cuts the richness of the fish.
The step that matters
Bring the sauce to a boil before adding the mustard and pouring. The flour needs to be fully heated in the liquid to thicken the sauce properly, and a smooth, hot sauce coats the fish evenly without becoming lumpy or thin.
Swap the mace
How well each one fits the dish's main ingredients (flour, butter, pepper, port wine, mustard):
- Capersfits better
- Tarragonfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against flour, butter, pepper, port wine, mustard. Candidates are from the same food group and used in at least 100 recipes.
