To a frying pan or skillet over medium heat, add the unsalted butter. When the butter is warm, crack each egg first into a small bowl and then transfer it to the pan or skillet.
Using a spoon, scoop up the warm butter and pour it over the top of the eggs (basting them with the butter).
Add a pinch of salt, pepper, and chili flakes.
Continue basting the eggs with the butter until they’re cooked to your liking. You can serve them sunny side up or flip them in the pan and cook until they’re over easy, over medium, or over well (depending on your preference) (note 3).
