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 ↓
Potato Croquettes
Ingredients
Directions
Make the potato mixture

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Forms the bulk of the croquettes and gives them a soft, moist interior.
- Egg yolks
- Bind the potato mixture and help it hold its shape when cooked.
- Butter
- Adds richness and moisture to the mixture.
- Cream
- Adds moisture and smoothness to the potato mixture.
- Bread crumbs (in the method)
- Form a crisp, golden-brown outer coating when fried.
The step that matters
Cook until the mixture leaves the sides of the pan. Cooking drives off excess moisture so the mixture is firm enough to shape. If it is too wet, the croquettes may slump or burst open in the hot fat.
Swap the onion
How well each one fits the dish's main ingredients (potato, cream, egg, parsley, butter, pepper):
- Chivefits better
- Spinachfits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against potato, cream, egg, parsley, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
