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 ↓
Puffy 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
Prepare all utensils, including the serving plate.
Make the egg mixture
Beat the egg yolk vigorously in a bowl, then add salt, pepper, and cold water.
Gently fold in the stiffly beaten egg whites, which should also have salt added.
Cook and serve
Melt the butter in a hot omelet pan.
Pour the egg mixture into the pan and shake gently over the flame until the bottom is slightly browned.
Transfer the pan to a 400°F (200°C) oven to cook the top.
Fold the omelet and serve on a hot plate.

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
- Egg
- Egg whites trapped by beating give the omelette its light, puffy structure as they set.
- Butter
- Melted butter coats the hot pan and adds richness and browning to the base.
- Cold water
- Cold water adds moisture to the mixture, producing steam that helps the omelette puff.
The step that matters
Folding in the stiffly beaten egg whites. Egg whites hold air only while stiff; overmixing or heavy folding deflates them. Gentle folding keeps the air bubbles that make the omelette puffy when it cooks.
“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.
