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 ↓

Ingredients
Directions
Prepare
Heat a little sweet oil or butter in a small frying pan.
Cut up the meat of two medium sized tomatoes, some green shallot and green sweet pepper; cut them up very fine.
Add one third of a tablespoonful of "Chile Powder," then break two fresh eggs into this and season with salt; mix well and serve very hot.
Beat the whites and yolks of four or six eggs separately.
Make and bake the omelette
Add to the yolks a small cup of milk, a tablespoon of flour or cornstarch, a teaspoonful of baking powder, one-half teaspoonful of salt and lastly the stiff beaten whites.
Put a heaping tablespoonful butter in a deep granite pan, set on stove until it melts then pour the omelet into same and bake in a steady oven for twenty minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trap air for lift and yolks add richness and structure as the omelette sets.
- Baking powder
- Releases gas in the batter, helping the omelette rise and stay light in the oven.
- Flour
- Starch gives the batter body so it holds its shape rather than collapsing.
- Milk
- Adds moisture and softness to the custard-like batter.
- Tomatoes
- Add moisture and a fresh, slightly acidic flavour to the filling.
The step that matters
Folding in the stiff beaten whites. Whites hold air only while whipped; overmixing deflates them, so fold gently and bake promptly to keep the omelette light.
Swap the tomato
How well each one fits the dish's main ingredients (milk, flour, egg, tea, pepper):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Tomatothe original
Fit is the average pairing score against milk, flour, egg, tea, pepper. Candidates are from the same food group and used in at least 100 recipes.
