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 ↓
Egg 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 batter
Beat the egg whites and yolks separately.
Warm the milk enough to melt the butter, then add it to the yolks.
Make a paste with the flour and a little of the milk.
Fold in the beaten egg whites last.
Bake
Bake in a deep dish or shallow pans at 400°F (200°C) and fold it over after it browns.
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.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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 for lift, while yolks add richness and help set the structure.
- Milk
- Adds moisture and softness, diluting the eggs so the omelet stays tender.
- Butter
- Adds fat for richness and flavor, and helps the surface brown.
- Flour
- Thickens the paste and gives the omelet body so it holds together when folded.
The step that matters
Fold in the beaten egg whites last. Beaten whites hold air that makes the omelet light. Stirring them too hard or too long deflates the foam, leaving a dense, flat result.
