Why it works: Egg and butter are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 118,967 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Omelette, with Tomatoes
Ingredients
Directions
Prepare
Beat the eggs just enough to break up the yolks.
Heat the butter in a frying pan until melted.
Cook and fill
Pour the eggs into the pan and shake to loosen from the sides and bottom.
When the eggs are set in the middle, cover one half with hot stewed tomatoes.
Fold the other half over to enclose the tomatoes.
Serve
Invert the pan onto a hot dish to serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a tender structure that holds the omelette together around the filling.
- Butter
- Coats the pan so the eggs release cleanly and add richness to the flavour.
- Stewed tomatoes
- Provide moisture and acidity that contrast with the rich, set eggs.
The step that matters
Shaking the eggs while they set. Shaking loosens the eggs from the pan so they do not stick. Eggs cooked over high heat without movement can toughen and brown unevenly, so the middle should set gently.
Swap the tomato
How well each one fits the dish's main ingredients (egg, butter):
- Asparagusfits better
- Chivefits better
- Leekfits better
- Tomatothe original
Fit is the average pairing score against egg, butter. Candidates are from the same food group and used in at least 100 recipes.
