Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set on heating to thicken the mixture and give it a soft, custard-like body.
- Tomatoes
- Provide moisture, acidity and fresh flavor that cuts through the rich butter and eggs.
- Butter
- Adds fat for richness, smooth mouthfeel and a buttery flavor to the dish.
The step that matters
Stirring the eggs into the hot mixture. Egg proteins begin to set around 70 to 80 °C and can curdle if the heat is too high or stirring stops. Keep the heat moderate and stir constantly until the mixture thickens smoothly.
Swap the tomato
How well each one fits the dish's main ingredients (egg, butter, pepper):
- Capsicumfits better
- Asparagusfits better

- Tomatothe original
Fit is the average pairing score against egg, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
