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

What each ingredient does

Potatoes
Form the main body of the pancake and, once grated, provide starch that crisps when fried.
Eggs
Bind the grated potato together so the pancakes hold their shape.
Onion
Adds savory flavor to the batter.
Flour
Absorbs moisture and helps the batter hold together.

The step that matters

Heat the fat until very hot before adding the batter. Hot fat sears the outside of the batter quickly, forming a crisp crust and limiting oil absorption. Cool fat lets the batter soak up grease and turn soggy and heavy.

Swap the onion

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

  1. Chivefits better
  2. Asparagusfits better
  3. Leekfits better
  4. Onionthe original

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