Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Cheese Omelet
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the eggs
In a bowl, beat the yolks of the eggs until light and creamy.
Add salt, pepper, and milk to the yolks and mix well.
In another bowl, beat the egg whites until stiff but not dry.
Gently fold the egg whites into the yolk mixture.
Cook and serve
Melt 2 tablespoons of butter in a frying pan over medium heat.
Pour the egg mixture into the pan and spread it evenly.
When the omelet is set, sprinkle the grated cheese on top.
Transfer the omelet to a preheated oven at 400°F (200°C) for a few minutes to dry the top.
Fold the omelet and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trap air for lift, while yolks add richness and set the body of the omelet.
- Grated cheese
- Melts into the eggs, adding fat, savory flavor and a creamy texture.
- Milk
- Adds moisture and softness, keeping the omelet tender rather than dry.
- Butter
- Fat for frying that prevents sticking and adds rich, browned flavor to the surface.
The step that matters
Gently fold the egg whites into the yolk mixture.. Whites are full of trapped air that gives the omelet its lift. Stirring or pressing them hard deflates the foam, leaving a dense, flat result.
