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 ↓
Sweet Potato Croquettes
Ingredients
Directions
Prepare
Combine hot riced sweet potatoes, butter, salt, pepper, and beaten egg in a bowl.
If the potatoes are very dry, add hot milk to moisten.
Shape and coat
Shape the mixture into croquettes.
Dip each croquette in bread crumbs, then in beaten egg, and again in bread crumbs.
Fry and drain
Fry the croquettes in deep oil until golden brown, then drain on paper towels.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet potatoes
- Provide the bulk and starchy body that holds the croquette shape.
- Butter
- Adds richness and moisture to the soft interior.
- Egg
- Binds the mixture so the croquettes hold together, and helps the crumb coating adhere.
- Bread crumbs
- Form a crisp, browned outer crust when fried.
The step that matters
Frying in deep oil until golden brown. The oil must be hot enough to crisp and brown the crumb coating quickly. If it is too cool, the croquettes absorb oil, turn greasy, and the interior can fall apart before the crust sets.
Swap the sweet potato
How well each one fits the dish's main ingredients (butter, pepper, egg, bread):
- Capsicumfits better
