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 ↓
Eggs with Tomatoes
Ingredients
Directions
Make the tomato base
In a skillet, brown the minced onion in the butter.
Stir in the flour and cook until it bubbles.
Add the tomatoes and bring to a boil.
Add the eggs
Beat the eggs together and slowly stir them into the boiling tomato mixture.
Cook until the eggs thicken, then season with salt and pepper before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set and thicken into soft curds that give the dish its body.
- Tomatoes
- Provide the main liquid and a tangy, acidic flavour base.
- Butter
- Adds fat and richness and helps brown the onion.
- Flour
- Thickens the tomato liquid slightly before the eggs go in.
- Onion
- Adds savoury depth as it browns in the butter.
The step that matters
Stirring the eggs into the boiling tomatoes. Adding the beaten eggs slowly keeps them from clumping into lumps. Egg proteins set with heat, so pouring them into a steadily boiling mixture while stirring helps them form fine, even curds.
Swap the tomato
How well each one fits the dish's main ingredients (egg, butter, flour, onion, pepper):
- Chivefits better
- Leekfits better
- Shallotfits better
- Tomatothe original
Fit is the average pairing score against egg, butter, flour, onion, pepper. Candidates are from the same food group and used in at least 100 recipes.
