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

What each ingredient does

Boiled potatoes
Form the starchy bulk of the croquette and, once mashed, bind into a shapeable mixture.
Butter
Adds richness and fat, giving the filling a softer, more tender texture.
Egg yolk
Acts as a binder that helps the potato mixture hold its shape.
Egg
Beaten egg forms a coating that helps breadcrumbs stick to the croquettes.
Breadcrumbs
Form a crisp outer crust that browns during frying.

The step that matters

Fry in hot oil until golden brown. If the oil is not hot enough, croquettes absorb excess oil and turn greasy, while the coating may fall off. Hot oil quickly sets the crust so it browns and seals the filling.

Swap the potato

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

  1. Shallotfits better
  2. Chivefits better
  3. Leekfits about as well
  4. Potatothe original

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