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

What each ingredient does

Eggs: Set when cooked, forming the structure that holds the omelet together.
Cooked vegetables: Provide the main filling and moisture, mashed into a puree for spreading.
Milk, cream, or gravy: Adds moisture and richness to the vegetable puree so it spreads smoothly.
Butter: Fat for the pan that adds flavor and helps keep the eggs from sticking.

The step that matters

Pour the beaten eggs into the pan and cook until set. Eggs turn firm as their proteins coagulate with heat. Cooking too hot or too long makes them tough and dry, while stopping before they set leaves the omelet too runny to fold.

Swap the cucumber

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