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 omelet's structure and tender body when cooked.
Cooked vegetables: Provide the filling, adding moisture, flavor and body to the omelet.
Butter: Adds richness and helps keep the omelet from sticking to the pan.
Milk, cream, or gravy: Loosens the vegetables into a spreadable puree and adds moisture.

The step that matters

Cook the eggs until just set. Eggs turn rubbery when overcooked, and the omelet needs enough set structure to fold without tearing around the filling.

Swap the cucumber

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