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

What each ingredient does

Cold mashed potatoes: Form the bulk of the croquette and give a soft, tender interior.
Egg yolk: Binds the mixture so the croquettes hold their shape.
Egg white: Acts as an adhesive so the crumbs stick to the surface.
Butter: Adds fat for richer flavor and a softer texture inside.
Cream: Adds moisture and makes the mixture easier to shape.
Cracker or bread crumbs: Form a crisp, golden coating that browns during frying.

The step that matters

Chill and firm the shaped croquettes before frying. The mixture is soft and moist, so croquettes can break open or absorb excess oil if they are not firm. Keeping them cool helps the coating set and hold together while frying.
