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
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
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 part of the stove to cook the omelet more slowly.
When the edges are set, optionally place the pan in a 350°F (175°C) oven for 1 minute to set the center.
Serve
Fold the omelet in half or thirds and turn it onto a hot dish.
Garnish with parsley and serve immediately.

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 trapped by folding create air that gives the omelette its light, puffy structure.
- Milk
- Adds moisture and dilutes the egg proteins, keeping the omelette tender rather than rubbery.
- Flour
- Helps stabilise the egg mixture so it stays creamy and holds together when cooked.
- Butter
- Greases the pan to prevent sticking and adds rich flavour and gentle browning.
The step that matters
Cooking over a cooler part of the stove. Egg proteins set quickly under high heat and turn tough or brown. Moving the pan to gentler heat lets the omelette cook slowly and stay tender.
