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

What each ingredient does

Eggs
Set to form the body of the omelette as they cook.
Potato
Adds bulk and a soft, tender texture inside the omelette.
Butter
Adds richness and helps keep the omelette from sticking to the pan.

The step that matters

Cook the omelette until set, then fold and serve immediately.. Eggs turn firm as their proteins coagulate with heat. Removing the omelette once just set keeps it tender, while overcooking makes it dry and rubbery. Folding and serving right away keeps it soft.

Swap the potato

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

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

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