Cut very small scallions, grate mozzarella in threads and grate a little Parmigiano Reggiano cheese very fine (Sardo is nice too).
5 grams grated Parmigiano Reggiano, 50 grams grated Mozzarella cheese
Beat the eggs with the mozzarella and cheese well mixed and let them rest for a minute.
4 eggs
Cook the scallions for no more than 1 minute with a teaspoon of butter (A good tip is to use more butter to get a creamier omelette).
1 bunch green onions
Pour the mix to the pan and stir with a rubber spatula while moving the pan in circles to mix everything well and cook the eggs faster.
The point is very precise and it is very easy to overcook it if you are not careful, over a very high heat the egg cooks almost immediately.
Once the bottom of the egg is cooked and the top is still semi liquid/raw, fold it almost in half, leaving about 3 cm to seal the omelette when you turn it over.
It has to be cooked barely golden on the outside and a little liquid inside. We want a juicy omelette. That’s all!
