Dip each croquette in beaten egg, then coat with bread crumbs.
Fry

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf’s liver
- Forms the main body of the croquettes and gives them their rich flavor.
- Egg
- Binds the minced liver so the croquettes hold their shape.
- Bread crumbs
- Form a crisp, golden coating that browns during frying.
- Onion
- Adds aromatic sweetness and savory depth to the filling.
The step that matters
Frying in boiling lard. The lard must be hot enough to brown the crumb coating quickly. If it is too cool, the croquettes absorb extra fat and turn greasy before the crust sets.
Swap the onion
How well each one fits the dish's main ingredients (liver, pepper, parsley, sage, egg, bread):
- Carrotfits better
- Shallotfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against liver, pepper, parsley, sage, egg, bread. Candidates are from the same food group and used in at least 100 recipes.
