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

What each ingredient does

Eggs
Set when heated, binding the mixture into a tender omelette.
Tomatoes
Add moisture and a fresh acidity that brightens the eggs.
Grated bread
Absorbs tomato liquid, helping the omelette hold together and stay soft.
Onion
Adds savory sweetness and aroma as it softens in the mixture.

The step that matters

Stirring rapidly until it begins to thicken. Constant stirring breaks the egg into small curds while it sets, giving a soft texture; if left still, the bottom overcooks before the top sets.

Swap the onion
