Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set when cooked, giving the omelet its structure and body.
- Milk
- Adds moisture and softness to the beaten eggs, keeping the omelet tender.
- Tomato
- Provides the main flavor and moisture of the sauce poured over the omelet.
- White sugar
- Balances the acidity of the tomatoes, adding sweetness to the sauce.
The step that matters
Cook the egg mixture in a skillet to form a nice omelet. Eggs turn from liquid to set protein as they heat, so high heat or overcooking makes them tough and dry, while gentle heat keeps them tender enough to roll.
Swap the tomato
How well each one fits the dish's main ingredients (butter, pepper, sugar, egg, milk):
