Why it works: Pepper and tomato 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 Tomato Sauce
Ingredients
Directions
Fry the eggs
Heat the salad oil in a small frying pan until it is smoking hot.
Tilt the frying pan to gather the oil in one place.
Gently slide a broken egg, seasoned with salt and pepper, into the hot oil.
Wrap the egg white over the yolk to form a roll, being careful not to break the yolk.
Once cooked, place the egg on a clean cloth to drain.
Repeat until you have the desired number of eggs.
Serve
Serve the eggs on a dish and pour thick tomato sauce around them.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set and form the main body of the dish, with the white wrapping the yolk.
- Salad oil
- Conducts heat to cook the eggs quickly and gives the whites a crisp, fried edge.
- Tomato sauce
- Adds moisture and acidity alongside the rich eggs.
The step that matters
Wrapping the egg white over the yolk. The white must set enough to hold its shape while the yolk stays soft. Folding too early or too late can break the yolk and spill its runny contents into the oil.
Swap the tomato
How well each one fits the dish's main ingredients (egg, pepper, sauce):
- Capsicumfits better
- Spinachfits better
- Asparagusfits about as well
- Tomatothe original
Fit is the average pairing score against egg, pepper, sauce. Candidates are from the same food group and used in at least 100 recipes.
