Foamy Omelet

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 the egg

  1. Beat the yolk of the egg until light and creamy.

  2. Add the salt, pepper, and milk to the yolk and mix well.

  3. Beat the egg white until stiff but not dry.

  4. Gently cut and fold the beaten egg white into the yolk mixture.

Cook and serve

  1. Heat an omelet pan and add the butter, coating the sides and bottom.

  2. When the pan is very hot, pour in the omelet mixture and spread it evenly.

  3. Reduce the heat and cook until the omelet is set.

  4. Transfer the omelet to a 400°F (200°C) oven for a few minutes to dry the top slightly.

  5. Fold the omelet, garnish with parsley, and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg
Whites trapped with air give the omelet its foamy, light structure, while the yolk adds richness.
Butter
Coats the pan so the omelet releases easily and adds richness and browning.
Milk
Adds moisture to the yolk mixture, keeping the omelet tender rather than dry.

The step that matters

Folding the egg white into the yolk. Cutting and folding gently keeps the air bubbles in the whipped whites. Stirring or deflating them makes the omelet dense and flat instead of light and foamy.
