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

What each ingredient does

Potatoes
Provide the starchy bulk that gives the pancakes their body and crisp exterior.
Onion
Adds moisture and savory aroma that deepens as the pancakes fry.
Flour
Absorbs liquid from the grated vegetables and helps the pancakes hold together.
Egg
Binds the grated potato and onion so the mixture holds its shape in the pan.

The step that matters

Cook until crisp and then turn over. Grated potato releases starch and water, so the pancake needs enough oil and steady heat to brown and crisp. Turning too early may tear it apart before a firm crust forms.

Swap the onion

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

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

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