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 ↓
Egg Souffle
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the eggs
Separate the egg whites and yolks, then beat them together until combined.
Add salt, pepper, and Worcestershire sauce to the egg mixture.
Cook
Heat a pan on the stove and add the butter. Wait until it is hot and hissing but not browned.
Pour the egg mixture into the hot pan. Pull the pan back and let it sit until the eggs puff and stiffen, lifting from the bottom with a knife to prevent scorching.
Transfer the pan to a 400°F (200°C) oven for 1 minute to form a crust.
Serve
Fold the souffle and serve immediately on a dish garnished with parsley.

Sauce and butter 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
- Whites trap air to give the soufflé its light, puffed structure, while yolks add richness and set as it cooks.
- Butter
- Fat in the hot pan starts the egg mixture cooking from below and helps prevent sticking.
The step that matters
Pour the egg mixture into the hot pan and let it set without stirring. The pan must be hot enough that the eggs begin setting on contact, which lets the base puff and stiffen. Lifting the base with a knife helps prevent scorching while the bottom sets.
Swap the parsley
How well each one fits the dish's main ingredients (egg, pepper, sauce, butter):
- Parsleythe original
- Tarragonfits about as well
- Capersfits about as well
- Nutmegfits less well
Fit is the average pairing score against egg, pepper, sauce, butter. Candidates are from the same food group and used in at least 100 recipes.
