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 ↓
Tomato Toast
Ingredients
Directions
Make the tomato mixture
Slice the tomatoes and place them in a pan with the butter. Fry for five minutes.
Rub the mixture through a fine sieve and return the pulp to the pan.
Break in the eggs, then add the seasoning, sugar, and vinegar. Stir over gentle heat until it begins to set.
Assemble and serve
Cut the bread into small rounds or squares and butter them.
Place a little of the tomato mixture in the center of each piece of toast.
Arrange the toast on a dish, stacking them, and garnish with parsley or cress before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main flavour and the pulp that forms the body of the mixture.
- Eggs
- Set with gentle heat to thicken the tomato pulp into a spoonable topping.
- Butter
- Adds richness and helps fry the tomatoes, carrying flavour into the pulp.
- Vinegar
- Adds a small amount of acidity that brightens the sweetness of the tomatoes.
The step that matters
Stir the eggs over gentle heat until they just begin to set. Egg proteins set at moderate temperatures and turn grainy or scrambled if overheated. Gentle heat, with constant stirring, thickens the mixture smoothly.
Swap the tomato
How well each one fits the dish's main ingredients (egg, butter, pepper, vinegar, sugar):
- Capsicumfits better
