Plain Omelet

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the eggs

  1. Beat the egg yolks until thick and light.

  2. Add salt and pepper to the yolks.

  3. Beat the egg whites until stiff and dry.

  4. Add hot water to the yolks.

  5. Gently fold in the beaten egg whites.

Cook and finish

  1. Melt butter in a hot omelet pan.

  2. Pour in the egg mixture and spread evenly.

  3. Cook slowly on the stovetop until well puffed, carefully tilting the pan to ensure even rising.

  4. Transfer to a 350°F (175°C) oven to finish cooking until firm to the touch.

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

What each ingredient does

Egg whites
Whipped to stiffness, they trap air and give the omelet its light, puffed structure.
Egg yolks
Beaten until thick, they add richness and body that holds the fold together.
Butter
Melted in the hot pan, it adds fat for flavour and helps prevent sticking.
Hot water
Adds moisture that turns to steam during cooking, helping the omelet puff.

The step that matters

Gently fold in the beaten egg whites. Overmixing collapses the air bubbles in the whipped whites, so the omelet loses its lift and turns dense instead of puffed.
