Beat the eggs with the salt in a mixing bowl until smooth and no spots of egg white remaining.
Strain the egg mixture through a sieve.
Add 1 tablespoon of butter into a non-stick skillet over medium heat. Once melt, pour in the egg mixture.
Constantly scrape the bottom of the pan in a circular motion, using a rubber spatula. Cook for about 1-2 minutes until small curds form.
Spread the eggs evenly in the pan, and cook until the edges solidify.
Roll the omelette carefully into a log shape. Make sure the eggs are not overcooked. It’s normal if the egg rolls are not perfectly folded.
Add more butter to the pan and lift the omelette to let the melted butter run underneath.
Brush more melted butter on top of the omelette.
Transfer the omelette onto a plate, seam side facing down. Sprinkle with optional herbs. Serve immediately and enjoy!
