Name: Cheese Omelet
Ingredients: ⅔ cup milk; 4 eggs; ½ to 1 cup grated cheese; 1 tablespoon flour; butter

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 the batter

Beat the eggs in a bowl.
Mix the flour with a little cold milk until smooth.
Combine the egg mixture with the flour mixture, then stir in the grated cheese.

Cook and serve

Pour the mixture into a hot buttered pan.
Bake in a 400°F (200°C) oven until set.
Roll the omelet and serve.

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: Set into the structure of the omelet as they cook.
Flour: Thickens the batter so the omelet holds together when rolled.
Milk: Adds moisture and keeps the omelet tender as the eggs set.
Grated cheese: Adds richness and flavor, and melts through the set eggs.

The step that matters

Bake in a 400°F (200°C) oven until set. Egg proteins coagulate with heat, so the omelet turns firm and rollable once set. Overbaking squeezes out moisture and makes it dry and rubbery, while underbaking leaves it runny and likely to tear when rolled.
