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 ↓
Mackerel Stewed with Wine
Ingredients
Directions
Make the sauce

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mackerel
- The main protein, which is gently cooked in the wine sauce until tender.
- Butter
- Adds fat and richness to the base of the sauce.
- Flour
- Thickens the butter and wine into a smooth, cohesive sauce.
- Claret
- Provides the liquid and wine flavour that the fish stews in.
- Prepared mustard
- Adds sharpness and a tangy edge that cuts through the richness of the sauce.
The step that matters
Whisking the flour into the butter. Flour must be fully mixed into the melted butter and cooked briefly before the liquid goes in. Otherwise lumps form and the sauce stays floury and dull. Adding the wine gradually keeps the sauce smooth as it thickens.
Swap the mace
How well each one fits the dish's main ingredients (butter, flour, pepper, port wine, mustard):
- Capersfits better
- Tarragonfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against butter, flour, pepper, port wine, mustard. Candidates are from the same food group and used in at least 100 recipes.
