How many Egg whites equal one whole egg in an omelette?

You can't exactly replace a whole egg with egg whites in an omelette. Here's why:

* Texture: Egg yolks provide fat and richness, giving an omelette its fluffy, creamy texture. Egg whites are mostly protein, which will make your omelette thinner and more rubbery.

* Flavor: Egg yolks contribute to the taste of the omelette. Egg whites have a very mild flavor.

Instead of replacing a whole egg with just egg whites, here are some options:

* Use fewer whole eggs: You can make a thinner omelette with fewer whole eggs, but still get that richness and texture.

* Add milk or cream: Adding a tablespoon or two of milk or cream to your egg whites will help make them more fluffy and add a bit of richness.

* Use a combination: Try using 1-2 whole eggs and then supplementing with egg whites to reach your desired consistency.

Ultimately, the best way to find the right ratio for you is to experiment!
