Why it works: Bread and butter 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 Croquetts
Ingredients
Directions
Prepare the potato mixture
Cook the potatoes until soft, then strain them through a colander.
Mix in the eggs one at a time without beating.
Add the bread crumbs, a little butter, and salt to the potatoes.
Place the mixture over low heat and stir for a few minutes.
Shape and fry
Allow the mixture to cool, then roll it into balls.
Fry the balls 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
- Potatoes
- Provide the starchy bulk that gives the croquettes their soft, tender interior.
- Eggs
- Bind the mixture so it holds its shape when rolled and fried.
- Bread crumbs
- Absorb moisture and add body so the mixture is firm enough to shape.
- Butter
- Adds richness and flavor to the potato mixture.
The step that matters
Mixing in the eggs without beating. Beating the eggs incorporates air and can make the mixture loose and sticky; gentle mixing keeps it cohesive so the balls hold together in the hot lard.
Swap the potato
How well each one fits the dish's main ingredients (egg, bread, butter):
- Asparagusfits better
- Leekfits better
- Chivefits about as well
- Potatothe original
Fit is the average pairing score against egg, bread, butter. Candidates are from the same food group and used in at least 100 recipes.
