Why it works: Pepper and tomato 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 ↓
Devilled Tomatoes
Ingredients
Directions
Prepare the tomatoes
Pour boiling water over the tomatoes to loosen the skins, then peel and slice them thickly.
Make the sauce
Cream the butter, then mix in the powdered sugar and mustard until well combined.
Add the salt and pepper, then rub in the yolk of a hard‑boiled egg using a sieve.
Heat the vinegar and mix it into the sauce, then add a beaten raw egg.
Set the sauce over hot water and cook until it thickens to a cream‑like consistency.
Cook and serve
Fry the tomato slices in butter, pour the sauce over them, and serve hot or cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raw egg
- Thickens the sauce as it cooks, giving it a creamy body.
- Butter
- Adds richness and fat, and helps the tomato slices brown when fried.
- Hot vinegar
- Adds acidity that sharpens the sauce and balances the sweetness and richness.
- Mustard
- Adds sharp, pungent flavour that gives the sauce its characteristic bite.
- Tomatoes
- Provide the main body, moisture and acidic fruit flavour of the dish.
The step that matters
Cook the sauce over hot water until it thickens. Raw egg proteins set when heated, but too much direct heat can scramble the egg. Gentle hot-water heat lets the sauce thicken smoothly into a cream.
Swap the tomato
