Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet potatoes
- Mashed starch gives the croquettes body and a soft, moist interior.
- Butter
- Adds fat for richness and a smooth, tender texture.
- Egg
- Binds the coating so the crumbs stick, and sets to help hold the shape.
- Bread crumbs
- Form a crisp, browned crust when fried.
The step that matters
Fry in hot oil. Hot oil sets and browns the crumb coating quickly, so it crisps before it can soak up grease. Oil that is too cool lets the croquettes absorb fat and turn heavy and greasy.
Swap the sweet potato
How well each one fits the dish's main ingredients (butter, pepper, egg, bread):
- Capsicumfits better
- Asparagusfits better
- Chivefits better
- Sweet potatothe original
Fit is the average pairing score against butter, pepper, egg, bread. Candidates are from the same food group and used in at least 100 recipes.
