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

What each ingredient does

Potatoes
Form the bulk of the cake, giving body and a soft, moist interior.
Eggs
Bind the mashed potato so the cakes hold their shape while frying.
Butter
Adds richness and flavor, and moisture to the mashed potato.
Flour or cracker dust
Forms a dry coating that browns in hot oil and gives a crisp outer crust.

The step that matters

Let the mixture cool before shaping. Warm mashed potato with egg is soft and sticky, so it is hard to shape and may fall apart. Cooling firms the mixture and lets the cakes hold their form through coating and frying.

Swap the potato

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

  1. Chivefits better
  2. Shallotfits better
  3. Leekfits better
  4. 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.
