Why it works: Tomato and pepper are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Fried Eggs with Tomatoes
Ingredients
Directions
Fry
Break the eggs carefully into a pan filled with boiling oil or butter.
Fry the eggs until the whites are crisp.
Divide the tomatoes and fry them lightly in the butter.
Serve

Serve very hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set and crisp in hot fat, forming the main body of the dish.
- Tomatoes
- Soften in butter and add moisture and a mild acidity beneath the eggs.
- Oil or butter
- Conducts heat to cook and crisp the eggs and tomatoes, adding richness.
The step that matters
Break the eggs carefully into the boiling fat. Eggs dropped into very hot fat can spread and splatter, and breaking them gently keeps the whites compact so they set and crisp in neat, even shapes.
Swap the tomato
How well each one fits the dish's main ingredients (egg, butter, pepper):
- Capsicumfits better
- Asparagusfits better
- Chivefits better
- Tomatothe original
Fit is the average pairing score against egg, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
