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 ↓
Bacon Omelet
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Mince the bacon finely and place it in a pie dish.
Bake the bacon for a few minutes.
Make the batter
Beat the egg yolks.
Add the flour, onion, green chillies, milk, and salt to the yolks.
Beat the egg whites until stiff.
Fold the beaten whites into the yolk mixture.
Bake
Pour the batter over the bacon in the dish.
Bake for 20 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 give the omelet its light, airy structure, and the yolks add richness.
- Flour
- Thickens the batter so it holds its shape around the bacon and onion.
- Milk
- Adds moisture and softness, helping the batter set into a tender custard.
- Lean bacon
- Provides savory, salty flavor and fat that bakes into the dish.
- Onion
- Adds sweetness and aroma as it cooks into the batter.
The step that matters
Fold the beaten whites into the yolk mixture. Folding gently keeps the air in the whipped egg whites. Stirring or deflating them makes the omelet dense instead of light and puffed.
Swap the onion
How well each one fits the dish's main ingredients (egg, flour, milk):
- Arrowrootfits better
- Asparagusfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against egg, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
