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.
Thick white sauce
Binds the minced ingredients together so the mixture holds its shape.
Bread crumbs
Form a crisp outer crust that browns when fried.
Ham
Adds savory, salty flavor to the filling.
Anchovies
Contribute a deep savory note to the filling.
Cooked mushrooms
Add moisture and earthy flavor to the filling.

The step that matters

Letting the filling cool before shaping. A warm, loose mixture is soft and sticky, so the croquettes can slump or split. Cooling lets the white sauce firm up so the portions hold their shape and the coating stays intact during frying.
