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

What each ingredient does

Shrimps: Provide the main filling and the savory flavor of the croquettes.
Mayonnaise sauce: Binds the shrimp together and adds richness and moisture to the filling.
Aspic jelly: Sets into a clear savory gel that holds the dish together and adds moisture.
Bread and butter: Forms the base that holds the filling and adds a buttery, crisp foundation.
