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 says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Separate the yolks from the whites of the eggs.
Make the batter
Beat the yolks until smooth, then mix in the flour and milk.
In a separate bowl, beat the egg whites until stiff peaks form.
Gently fold the beaten egg whites into the yolk mixture.
Cook and serve
Melt the butter in a buttered pan over medium heat.
Pour the egg mixture into the pan and cook until set.
Fold the omelet in half and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trapped in beaten foam give the omelet its light, airy structure, and the yolks add richness.
- All-purpose flour
- Starch thickens the yolk mixture and gives the omelet a more stable, tender body.
- Milk
- Adds moisture and softness to the yolk base, keeping the omelet from drying out.
- Butter
- Fat coats the pan to prevent sticking and adds rich flavor and gentle browning.
The step that matters
Folding the beaten egg whites into the yolk mixture. Egg whites hold air only while whipped. Folding gently keeps that air in, so the omelet stays light. Stirring or deflating the whites makes the result dense and flat.
