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 body that holds the croquette together and gives it a creamy interior.
Butter
Adds fat for richness and a smoother, more tender texture in the mashed filling.
Egg
Binds the coating so the cracker crumbs stick and form a crisp shell.
Cracker crumbs
Form the outer crust that browns and crisps when fried.

The step that matters

Drop into boiling oil and cook until brown. If the oil is not hot enough, the coating absorbs oil and turns greasy instead of crisp, and the croquettes may fall apart. Hot oil sets the egg and crumb crust quickly, sealing the filling and driving browning.

Swap the sweet potato

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

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

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