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

What each ingredient does

Potatoes
Provide the bulk of the mixture and a soft, moist interior.
Egg yolks
Bind the mashed potato and add richness to the rolls.
Butter
Adds fat for richness and a softer, tender texture.
Cracker crumbs
Form a crisp, browned outer coating when fried.

The step that matters

Let the mixture cool before shaping. A warm, soft potato mixture is sticky and hard to shape, and it can fall apart or absorb too much egg and crumb. Cooling firms it so the rolls hold their form in the hot lard.

Swap the potato

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

  1. Leekfits about as well
  2. Spinachfits about as well
  3. Potatothe original
  4. Chivefits about as well

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