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

What each ingredient does

Potato
Forms the bulk of the croquette and gives a soft, moist interior.
Egg yolk
Binds the mixture so the croquettes hold their shape.
Butter
Adds richness and moisture to the mashed potato.
Bread crumbs
Form a crisp, golden outer crust when fried.

The step that matters

Fry in smoking-hot oil. Oil that is hot enough sets the crumb coating quickly and browns it before the interior absorbs much grease. Oil that is too cool lets the croquettes soak up fat and turn heavy and greasy.

Swap the onion

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

  1. Carrotfits better
  2. Chivefits better
  3. Spinachfits better
  4. Onionthe original

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