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
- Mashed potatoes
- Form the bulk of the rissole and give it a soft, tender interior.
- Egg
- Binds the mixture so the rissoles hold their shape when fried.
- Bread crumbs
- Form a crisp outer coating that browns during frying.
- Pickles
- Add sharp acidity that cuts through the richness of the potato.
The step that matters
Fry in dripping or butter until golden brown. Frying over moderate heat browns the bread-crumb coating through the Maillard reaction while the interior heats through. Too high a heat burns the crumbs before the centre is hot, and too low a heat makes the coating greasy and soft.
Swap the cucumber
How well each one fits the dish's main ingredients (potato, parsley, pepper, egg, bread, butter):

- Capsicumfits better
- Cucumberthe original
Fit is the average pairing score against potato, parsley, pepper, egg, bread, butter. Candidates are from the same food group and used in at least 100 recipes.
