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

What each ingredient does

Sardines
Provide the main fish body and savory flavor of the croquettes.
Hard boiled eggs
Yolks add richness and help bind the paste into a smooth mixture.
Bread crumbs
Absorb moisture and give the paste body, plus a crisp golden outer coating.
Beaten egg
Binds the mixture together and helps the crumb coating adhere.
Butter
Adds fat and richness to the mixture.

The step that matters

Forming and coating the balls. The paste must be firm enough to hold its shape and the egg and crumb coating must be even, otherwise the balls can break apart or leak in hot oil.

Swap the parsley

How well each one fits the dish's main ingredients (butter, egg, bread, pepper):

  1. Parsleythe original
  2. Nutmegfits about as well
  3. Sagefits less well
  4. Tarragonfits less well

Fit is the average pairing score against butter, egg, bread, pepper. Candidates are from the same food group and used in at least 100 recipes.
