Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Potato Croquettes
Ingredients
Directions
Make the mixture
In a bowl, combine the mashed potatoes, melted butter, white pepper, cayenne pepper, salt, celery salt, and onion juice.
Mix until very light and slightly cool, then add the egg yolk and mix well.
Rub the mixture through a sieve to ensure smoothness.
Shape and coat
Form the mixture into balls.
Roll each ball in fine bread crumbs, dip in beaten egg, then roll in crumbs again.
Fry
Fry the croquettes in hot lard until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Provide the bulk and soft body that the croquettes are formed from.
- Egg yolk
- Adds richness and helps bind the mixture so it holds its shape.
- Butter
- Adds fat and richness, softening the mashed potato texture.
- Bread crumbs (in the method)
- Form a crisp, golden outer crust when fried.
The step that matters
Frying in hot lard. If the fat is not hot enough, croquettes absorb oil and turn greasy before the crust sets; if too hot, the outside browns before the centre heats through.
Swap the white pepper
How well each one fits the dish's main ingredients (potato, butter, pepper, celery, onion, egg):
- Parsleyfits better
- Thymefits better
- Dillfits better
- White pepperthe original
Fit is the average pairing score against potato, butter, pepper, celery, onion, egg. Candidates are from the same food group and used in at least 100 recipes.
