Why it works: Egg and butter are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 118,967 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Foamy Omelet
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 yolks from the whites of the eggs.
Beat the yolks until thick, then add the salt, pepper, and water.
Beat the egg whites until very stiff, then fold the yolk mixture into the whites.
Cook and serve
Melt the butter in a hot pan, then reduce the temperature.
Pour the omelet mixture into the pan, spreading it evenly.
When the bottom is light and well browned, place it in a 400°F (200°C) oven to dry and firm on top.
Fold the omelet and serve immediately on a hot platter.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Egg and pepper barely smell alike, yet cooks put them together in 50,580 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 when beaten, giving the omelette its light, foamy structure as they set.
- Butter
- Fat that coats the pan and browns the base of the omelette for flavour.
- Water
- Adds moisture that turns to steam during cooking, helping the omelette puff and stay tender.
The step that matters
Fold the yolk mixture into the whites gently. Heavy folding or overbeating collapses the whipped whites and releases their trapped air, so the omelette turns dense instead of light and foamy.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
