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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold boiled potatoes
- Form the starchy base that holds the doughnut mixture together.
- Beaten egg
- Binds the balls and helps the cracker crumbs adhere as a coating.
- Cracker crumbs
- Form a crisp outer crust that browns during frying.
- Grated ham
- Adds savory, salty flavor throughout the mixture.
The step that matters
Fry the doughnuts in boiling fat until golden brown. The fat must be hot enough to brown the crumb coating quickly; if it is too cool, the doughnuts absorb excess fat and turn greasy, while overly hot fat can brown the outside before the interior heats through.
Swap the onion
How well each one fits the dish's main ingredients (potato, pepper, parsley, ham, egg):

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