Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet potatoes
- Provide the starchy, soft base that holds the croquette together and gives sweetness.
- Butter
- Adds fat and richness, making the mashed mixture smoother and more tender.
The step that matters
Fry the balls in hot oil until golden brown. If the oil is not hot enough, the croquettes absorb excess oil and turn greasy, while the breadcrumb coating browns unevenly. Hot oil sets the crust quickly, so the inside stays moist and the outside turns crisp and golden.
Swap the sweet potato
How well each one fits the dish's main ingredients (pepper, butter):
- Capsicumfits better
- Potatofits better
- Carrotfits better
- Sweet potatothe original
Fit is the average pairing score against pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
