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 ↓

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).
Beat the yolks and whites of the eggs separately.
Mix the flour, milk, and salt together.
Make and bake
Add the beaten yolks to the mixture, then gently fold in the beaten whites.
Grease a hot baking dish with butter.
Pour the mixture into the dish and bake for 5 minutes until golden brown.

Flour and butter 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 when beaten, giving the omelet its light, risen structure, while yolks add richness.
- Flour
- Starch thickens the milk and egg mixture so it holds its shape after baking.
- Milk
- Adds moisture and liquid that sets with the eggs into a tender custard-like texture.
- Butter
- Greases the hot dish so the omelet releases cleanly and begins to brown at the edges.
The step that matters
Folding in the beaten whites. Whites hold air in a foam that collapses if stirred vigorously. Folding gently with a spatula keeps the air bubbles intact, so the omelet rises rather than turning dense.
“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.
