Got a blender, mikey?
Place three eggs, two tablespoons of heavy cream, squidge of salt and pepper in the blender and mix until very frothy, about 1 minute.
Heat a sauté pan over medium heat and, when hot, add the butter to the pan, swirling to coat.
Pour the mixture into the pan. Using a rubber spatula, stir continuously and scrape down sides so as to evenly cook the mixture.
Once the mixture resembles wet scrambled eggs, after about 30 seconds, use the rubber spatula to smooth the eggs so that they are an even depth throughout.
Cook until almost set, about 10 seconds longer, and use the spatula to fold the omelette in half. Carefully slide the omelette out of the pan onto the plate.
If you want cheese or other fillings, in just before the fold.
