Why it works: Butter and milk 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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Add the milk.
Cook on the stove until it thickens into a sauce, then remove from heat.
Stir in the cheese.
Add the eggs
Beat the eggs.
Add the yolks.
Add the whites.
Pour the mixture into a baking dish.
Bake
Cook in the oven at 350°F (175°C) for 20 to 25 minutes.

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
- Flour
- Thickens the milk into a sauce as its starch swells when heated with liquid.
- Butter
- Adds fat and richness and coats the flour so it blends smoothly.
- Eggs
- Set in the oven to give the omelette its structure, with whites adding lightness.
- Cheese
- Adds savory flavor and fat, and melts into the sauce.
- Milk
- Provides the liquid that the flour thickens into a creamy base.
The step that matters
Cook the sauce until it thickens. Flour starch only thickens the milk fully once it is heated enough to swell. Stopping too early leaves the sauce thin and the flour tasting raw, while overheating can scorch it or make it lumpy.
