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 ↓
Omelette
Ingredients
Directions
Prepare the batter
Separate the yolks and whites of the eggs.
Beat the yolks until smooth, then add milk, salt, pepper, and flour; mix until creamy.
Beat the egg whites until stiff, then gently fold them into the yolk mixture until smooth.
Cook the omelette
Melt the butter in a medium-sized frying pan over medium heat.
Pour the egg mixture into the pan and let it sit for 1-2 minutes.
Loosen the edges with a knife and shake the pan occasionally to prevent sticking.
Move the pan to a cooler spot to cook more slowly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites give lift and airy structure, while the yolks add richness and set the omelette.
- Milk
- Adds moisture so the omelette stays tender rather than dry.
- Flour
- Helps stabilise the mixture so it holds together and stays creamy when cooked.
- Butter
- Fat that keeps the omelette from sticking and adds flavour.
The step that matters
Folding the whites into the yolk mixture. Overmixing knocks air out of the whipped whites, so the omelette turns dense instead of light. Fold gently, just until no streaks remain.
