Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Croquettes. Potato Croquettes.
Ingredients
Directions
Make the potato mixture
Melt the butter in a saucepan, add the milk, and bring to a boil.
Pass the mashed potatoes through a sieve and add to the boiling milk and butter.
Beat well until the potatoes are very hot, then remove from heat.
Stir in the pepper, salt, and cayenne, then add the egg yolks and mix until the heat dries the eggs.
Shape and coat
Form the mixture into small balls, using flour to prevent sticking.
Beat the egg whites and roll each ball in the whites.
Coat the balls in bread crumbs by rolling them on a sheet of kitchen paper.
Fry
Fry the croquettes in hot clarified fat or lard for 2 minutes.

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 croquettes, giving a soft, starchy interior that holds its shape.
- Butter
- Adds richness and fat, softening the potato mixture and improving flavour.
- Milk
- Adds moisture so the potato mixture becomes smooth and easy to shape.
- Eggs
- Yolks enrich and bind the mixture; whites form a coating that helps bread crumbs stick.
- Bread crumbs
- Form a crisp, golden outer crust when the croquettes are fried.
The step that matters
Mixing in the egg yolks until the heat dries them. The residual heat of the potatoes cooks the yolks gently. If the mixture is too cool, the eggs will not set and the balls may fall apart when frying; the mixture must still be warm enough to bind without scrambling.
Swap the potato
How well each one fits the dish's main ingredients (butter, milk, pepper, egg, bread):
- Capsicumfits about as well
- Potatothe original
- Asparagusfits about as well
- Tomatofits less well
Fit is the average pairing score against butter, milk, pepper, egg, bread. Candidates are from the same food group and used in at least 100 recipes.
