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 ↓
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.
Make the batter
In a bowl, combine the yolks of the eggs, flour, and milk.
Gently fold in the beaten egg whites.
Cook and brown
Heat butter in a frying pan over medium heat.
Pour the egg mixture into the pan and cook until it sets.
Transfer to a preheated oven at 400°F (200°C) to brown the top.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten whites trap air for lift, while the yolks add richness and set the structure.
- Flour
- Gives the batter body and helps hold the omelet together as it sets.
- Milk
- Adds moisture and makes the omelet softer and more tender.
- Butter
- Greases the pan and promotes browning and rich flavor on the surface.
The step that matters
Fold in the egg whites gently. Beaten egg whites hold air that gives the omelet its lift. Vigorous stirring deflates them, leaving the omelet dense and flat.
