Step 1

Whisk the egg, salt and mustard in a bowl.

Step 2

Melt the butter in a non-stick pan over medium heat. As soon as it is melted - and not browned - pour in the whisked egg. Turn the heat to low.

Step 3

Let the egg set for 20 seconds. Then begin to stir with a wooden spoon or spatula. Lift and fold the egg over from the bottom of the pan. Break down any larger pieces.

Step 4

Continue until the eggs are softly set and still runny in places. Take your time!

Step 5

Take the pan off the heat just BEFORE the eggs are finished. They will continue to cook in the hot pan.

Step 6

Give them a last stir and serve immediately!
