Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Mashed sweet potatoes
Form the main body of the croquettes and provide moisture and sweetness.
Egg
Binds the mixture so the patties hold their shape.
Breadcrumbs
Form a crisp, browned outer coating when fried.
Butter
Adds fat and richness to the sweet potato mixture.

The step that matters

Fry until golden brown on both sides. Medium heat lets the coating brown and crisp while the inside heats through. Too high a heat browns the breadcrumbs before the centre warms, and too low a heat leaves the coating greasy and pale.

Swap the sweet potato

How well each one fits the dish's main ingredients (butter, milk, pepper, egg):

  1. Capsicumfits better
  2. Potatofits better
  3. Asparagusfits better
  4. Sweet potatothe original

Fit is the average pairing score against butter, milk, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
