Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold fish
- Forms the main body of the savoury filling.
- Butter
- Carries flavour and keeps the fish moist as it heats through.
- Anchovy essence
- Adds a salty, savoury depth that stands out in the mixture.
The step that matters
Stir until thoroughly hot. The fish must be heated all the way through so it is safe to eat, but overheating dries and toughens its proteins. Gentle, steady stirring over gentle heat warms it evenly without drying it out.
Swap the mace
How well each one fits the dish's main ingredients (fish, butter, anchovy, parsley, pepper):
- Capersfits better
- Thymefits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against fish, butter, anchovy, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
