Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shredded codfish
- Provides the main flavor and the fish body of the balls.
- Mashed potatoes
- Bind the mixture and add moisture and softness inside the balls.
- Egg
- Binds the mixture together and forms a coating that helps browning.
- Butter
- Adds richness and fat that carries flavor and helps browning.
- Flour
- Dry coating that helps the egg layer stick and promotes browning when fried.
The step that matters
Fry the balls in hot oil until nice and brown. If the oil is not hot enough, the balls absorb oil and turn greasy, and the coating browns slowly. Hot oil sets the outside quickly, which keeps the inside moist and gives a crisp, golden crust.
Swap the potato
How well each one fits the dish's main ingredients (butter, egg, flour):
- Chivefits better
- Shallotfits better
- Leekfits better
- Potatothe original
Fit is the average pairing score against butter, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
