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 cakes and give a soft, starchy body once mashed.
Butter
Adds fat and richness, and softens the mashed potato for a smoother texture.
Egg
Binds the mashed potato so the cakes hold together when shaped and fried.
Lard
Conducts heat in the pan and promotes browning and a crisp, golden surface.

The step that matters

Drain nearly all the water from the potatoes before they are fully cooked. Letting the potatoes steam dry before mashing removes surface moisture. Wet potatoes make a loose mixture that is harder to shape and less likely to brown well in the pan.

Swap the potato

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

  1. Capsicumfits better
  2. Asparagusfits about as well
  3. Chivefits about as well
  4. Potatothe original

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