Why it works: Potato and parsley are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 2,855 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
- Fish
- Forms the main body of the dish, cooked gently in boiling water until tender and flaky.
- Potatoes
- Absorb flavour from the cooking water and add starchy bulk alongside the fish.
- Drawn butter
- Adds richness and fat that carries flavour and moistens the mild fish.
The step that matters
Lift the platter once the fish is tender. Fish cooked past tender becomes dry and falls apart, so checking for doneness and draining promptly keeps the flesh moist and intact.
Swap the parsley
How well each one fits the dish's main ingredients (fish, potato, butter):
- Parsleythe original
- Capersfits about as well
- Thymefits less well
- Tarragonfits less well
Fit is the average pairing score against fish, potato, butter. Candidates are from the same food group and used in at least 100 recipes.
