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 ↓
Egg and Tomato Toast
Ingredients
Directions
Prepare
Skin the tomatoes, slice them, and remove the seeds.
Melt 1 tablespoon of butter in a saucepan, add the eschalot (or onion) and tomato slices, and cook gently for 10 minutes.
Beat the eggs and season with pepper and salt.
Make the topping
Stir the eggs into the saucepan with the tomato mixture, and keep stirring until it thickens.
Serve
Prepare some buttered toast, and spread the mixture thickly on top.
Arrange the toast on a hot dish, garnish with parsley, and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set and thicken as they cook, giving the topping its body.
- Tomatoes
- Provide moisture and acidity that soften and flavour the savoury topping.
- Butter
- Adds richness and carries flavour while cooking the onion and tomato.
- Eschalot or onion
- Adds savoury aroma and sweetness as it cooks gently in butter.
The step that matters
Stirring the eggs into the tomato mixture. Over moderate heat, constant stirring keeps the eggs in fine curds so they thicken smoothly. If left unstirred, the egg proteins can set in lumps or scramble against the pan.
Swap the tomato
How well each one fits the dish's main ingredients (egg, onion, butter, pepper):
- Chivefits better
