Nothing is written about what the perfect omelette recipe looks like. More or less done, with or without onions, with the potatoes almost fried or not done at all, including more ingredients or just the classic, with more or less egg… That is why usually the first time the result is not as we expected. Making the perfect omelette takes time.
Even if this is a Spanish omelette with onions, you can simply leave them out. Furthermore, this time we include the amounts of the ingredients, but it is better to make it by eye, always keeping a proportion and balance between all its ingredients.
