Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold roast beef
- Provides the main body and savory flavor of the croquettes.
- Fresh breadcrumbs
- Absorb moisture and bind the mixture, giving it a softer interior.
- Egg yolk
- Binds the mixture together and adds richness to the filling.
- Egg white, whipped
- Forms a thin coating that helps the breadcrumbs adhere and brown evenly.
- Onion
- Adds moisture and savory aroma to the filling.
The step that matters
Fry in hot oil until golden brown. Hot oil quickly sets and browns the breadcrumb coating while heating the filling through. If the oil is too cool, the croquettes absorb grease and can turn soggy or fall apart.
Swap the onion
How well each one fits the dish's main ingredients (beef, pepper, egg):
- Capsicumfits better
- Asparagusfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against beef, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
