Egg and flour barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.

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 pancake, giving body and a starchy, tender interior when fried.
Eggs
Yolks bind the batter, while whipped whites lighten it and help the pancakes puff slightly.
All-purpose flour
Absorbs excess moisture and helps the grated potato hold together while frying.
Baking powder
Releases gas in the batter, adding lightness to the pancakes.

The step that matters

Gently fold in the beaten egg whites. Folding rather than stirring keeps the air trapped in the whipped whites, which keeps the batter light. Overmixing deflates the foam and produces dense pancakes.

Swap the potato

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

  1. Arrowrootfits better
  2. Chivefits better
  3. Shallotfits better
  4. Potatothe original

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