The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Hard-boiled eggs
Form the bulk of the filling and give the croquettes their body.
Milk
Moistens the filling and helps it thicken into a soft, spreadable mixture.
Flour
Thickens the milk into a binding sauce that holds the filling together.
Butter
Adds richness and flavor to the thickened filling.

The step that matters

Let the mixture cool in the refrigerator. The filling must be fully chilled and firm before shaping, or the cylinders will be soft and may break or leak during coating and frying.

Swap the onion

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

  1. Shallotfits better
  2. Chivefits better
  3. Potatofits better
  4. Onionthe original

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