Why it works: Flour and milk are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Omelet
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 egg whites and yolks separately.
Mix the flour, milk, and salt together.
Add the egg yolks to the mixture.
Gently fold in the beaten egg whites.
Cook
Preheat a skillet until very hot.
Pour the mixture into the skillet and bake at 400°F (200°C) for five minutes.

Flour and milk barely smell alike, yet cooks put them together in 78,219 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
- Whipped whites trap air for lift, while yolks add richness and help set the structure.
- Flour
- Provides some structure so the omelet holds together when cooked.
- Milk
- Adds moisture and softness to the cooked omelet.
The step that matters
Gently fold in the beaten egg whites. The whites hold the air that makes the omelet light. Stirring or mixing hard deflates the foam, so the result turns dense and flat. Fold slowly with a spatula, just until no white streaks remain.
