Why it works: Pepper and parsley 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 ↓
Potato Rissoles
Ingredients
Directions
Prepare
In a bowl, combine mashed potatoes, salt, pepper, and parsley if using.

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 rissoles and give them a soft, moist interior.
- Egg
- Binds the coating so the bread crumbs stick to each ball.
- Bread crumbs
- Form a crisp, golden coating that browns in the hot lard.
- Lard
- Conducts heat for frying and browns the crumb coating.
The step that matters
Fry the rissoles for about 2 minutes until golden brown. The crumb coating browns quickly in hot fat, so the pan must be hot enough to crisp the outside before the interior overheats or the coating burns. Watching for golden colour shows when the exterior has set and browned.
Swap the parsley
The recipe marks parsley as optional. How well each one fits the dish's main ingredients (potato, pepper, egg, bread, ham, onion):
- Parsleythe original
- Garlicfits about as well
- Thymefits less well
- Celeryfits less well
Fit is the average pairing score against potato, pepper, egg, bread, ham, onion. Candidates are from the same food group and used in at least 100 recipes.
