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 ↓
Deviled Tomatoes
Ingredients
Directions
Make the dressing
In a bowl, mix the butter and vinegar with the yolk of the hard‑boiled egg until smooth.
Add a pinch of sugar, salt, mustard, and cayenne pepper. Beat until smooth.
Heat to a boil. Remove from heat.
Pour the mixture over the well‑beaten egg, whipping to a smooth cream.
Prepare and serve
Slice the tomatoes into ½‑inch thick slices and lay them on a sieve.
Place the bowl with the dressing in hot water while broiling the tomatoes over a clear fire.
Serve the tomatoes on a hot dish. Pour the dressing over them.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Firm slices provide the base that holds up under broiling and the dressing.
- Butter
- Adds richness and a smooth, creamy body to the dressing.
- Vinegar
- Provides acidity that sharpens the flavor of the dressing.
- Egg yolk
- Emulsifies the butter and vinegar into a smooth, thick dressing.
- Well-beaten egg
- Thickens the dressing into a cream when whipped with the hot mixture.
The step that matters
Pour the mixture over the well-beaten egg, whipping to a smooth cream. Pouring hot mixture into beaten egg while whisking quickly warms the egg gradually, so it thickens smoothly. Pouring too fast or without whisking can scramble the egg and leave lumps.
Swap the tomato
How well each one fits the dish's main ingredients (butter, vinegar, egg, sugar, mustard, pepper):
