Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten eggs set when heated, giving the omelet its structure and body.
- Tomatoes
- Add moisture, acidity and sweetness to the filling.
- Butter
- Adds fat and rich flavor to the filling.
- Flour
- Binds with the butter and tomato juices to thicken the filling.
The step that matters
Fry in a hot frying pan. Eggs set quickly over high heat, so a pan that is too hot can brown and toughen the omelet before it cooks through. Keep the heat steady and moderate for a tender result.
Swap the tomato
How well each one fits the dish's main ingredients (butter, flour, egg, pepper):
- Chivefits better
- Shallotfits better
- Asparagusfits better
- Tomatothe original
Fit is the average pairing score against butter, flour, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
