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 ↓
Potato Croquettes
Ingredients
Directions
Prepare
Mash the potatoes well with the butter, pepper, salt, and a little of the beaten egg.
Flour your hands and form the mixture into desired shapes, such as fruits.
Coat and fry
Brush the shapes with beaten egg and cover them with bread crumbs.
Re-mould the croquettes after adding the crumbs.
Place them in a frying basket and fry until golden, similar to potato chips.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the croquette and give a soft, starchy interior that holds its shape.
- Butter
- Adds fat and richness, keeping the mashed potato moist and smooth.
- Egg
- Binds the mashed potato and, brushed on the outside, helps the bread crumbs stick.
- Bread crumbs
- Form a crisp outer coating that browns during frying.
The step that matters
Re-mould the croquettes after adding the crumbs. Bread crumbs stuck to a loose or damp surface can fall off in the fryer. Reshaping after coating presses the crumbs firmly onto the shape, so the coating stays intact while it fries.
Swap the potato
How well each one fits the dish's main ingredients (pepper, butter, egg, bread):
- Capsicumfits better
- Asparagusfits better
- Chivefits about as well
- Potatothe original
Fit is the average pairing score against pepper, butter, egg, bread. Candidates are from the same food group and used in at least 100 recipes.
