Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Omlet Truffle

Oven, in the book's wordsA hot oven

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

  1. Separate the egg whites from the yolks.

  2. Whisk the egg whites until frothy.

Make the batter

  1. Whisk the yolks with flour, sugar, and flavoring until well combined.

  2. Fold the egg whites into the yolk mixture gently.

Bake and serve

  1. Butter a baking dish and pour in the mixture.

  2. Bake in a hot oven at 400°F (200°C) until it rises high.

  3. Loosen from the dish and sprinkle sugar over it while still in the oven.

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, and yolks add richness and structure to the batter.
Flour
Gives the yolk mixture body so the risen foam holds its shape better.
Sugar
Sweetens the omelet and helps it brown lightly on the surface in the oven.

The step that matters

Fold the egg whites into the yolk mixture gently. Whites hold air only as long as they stay whole. Heavy stirring deflates the foam, so the omelet will not rise well in the oven.
