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
Provide the bulk and body of the filling that holds the croquette shape.
Butter
Adds richness and flavor to the base and helps form a smooth starting roux.
Flour
Thickens the butter and cream into a binding sauce that sets the filling.
Cream
Adds moisture and richness, loosening the thickened base into a creamy mixture.
Bread crumbs (in the method)
Form a crisp, golden coating that browns during frying.

The step that matters

Let the filling cool and firm before shaping. A warm, loose filling is soft and sticky, so croquettes can slump or split in the oil. Thickened starch sets as it cools, which holds the shape and keeps the coating intact during frying.

Swap the onion

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

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

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