Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold boiled fish
- Provides the main protein and flavour base that the croquettes are built around.
- Boiled rice
- Adds bulk and softness, helping the mixture hold together and stay moist inside.
- Egg
- Binds the coating so the bread crumbs stick and the croquette holds its shape.
- Bread crumbs
- Forms a crisp, golden browned crust when fried.
The step that matters
Frying the croquettes in hot oil. If the oil is not hot enough, the coating absorbs oil and turns greasy before it browns. Hot oil quickly sets the egg and crumb crust, sealing in moisture and producing an even golden colour.
Swap the parsley
How well each one fits the dish's main ingredients (fish, rice, pepper, egg, bread):
- Parsleythe original
- Turmericfits about as well
- Nutmegfits about as well
- Capersfits less well
Fit is the average pairing score against fish, rice, pepper, egg, bread. Candidates are from the same food group and used in at least 100 recipes.
