Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Buttered Eggs with Tomatoes
Ingredients
Directions
Prepare
Choose fine medium tomatoes; peel, cut off the tops, and remove the center.
Beat four eggs with three tablespoonfuls of cream and season with salt and pepper.
Set tomatoes in the oven to warm.
Warm two ounces of butter in a saucepan.
Make the filling
Pour the egg mixture into the saucepan.
Stir quickly until it begins to set.
Put the mixture into the tomato shells.
Bake and serve
Set in the oven for five minutes.
Serve on croutons of toast, sprinkle with parsley, and serve hot.

Shared aroma: trans-2-hexenal (green, leafy).
Butter and sauce barely smell alike, yet cooks put them together in 15,338 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set when heated, giving the filling its structure and body.
- Cream
- Adds moisture and richness, keeping the eggs soft and tender.
- Butter
- Adds fat and flavor and helps the eggs cook gently without sticking.
- Tomatoes (in the method)
- Hold the filling as edible shells and add a slight acidity.
The step that matters
Stir quickly until it begins to set. Eggs cook fast over heat. Stirring keeps curds small and soft, while letting them sit turns them dry and rubbery.
Swap the parsley
How well each one fits the dish's main ingredients (cream, butter, sauce, egg, pepper):
- Nutmegfits about as well
- Tarragonfits about as well
- Parsleythe original
- Capersfits about as well
Fit is the average pairing score against cream, butter, sauce, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
