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 Tomatos
Ingredients
Directions
Heat oil or butter in a pan until boiling.
Carefully break the eggs into the pan and fry until the whites are crisp.
Slice the tomatoes and fry them lightly in the same butter.
Place the fried tomatoes in a dish, sprinkle with pepper and salt, and lay the fried eggs over them.
Serve immediately while hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Form the main body of the dish; the whites set and firm as they fry.
- Tomatoes
- Add moisture and acidity that contrast with the rich fried eggs.
The step that matters
Fry the eggs until the whites are crisp. Cooking the whites at too high a heat can make them brown and tough before the yolks are done, while too low a heat leaves them pale and runny. Adding eggs gently to hot fat helps the whites set evenly at their edges.
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.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
