Heat an inch of water in a small saucepan over medium-high heat until boiling. Add the egg, reduce the heat to medium, and cover with a lid. Let the egg cook for 6 minutes then remove it from the stove. Side Note: if you are using a jumbo-sized egg, cook for 6 minutes & 30 seconds.
Run the saucepan and egg under cold water until the egg is cool enough to be handled. Using a knife, crack the top edge of the egg then gently peel, making sure to be careful so you don't puncture the egg.
Once it is peeled, place on a piece of buttered toast, slice down the center with a knife, season with sea salt and freshly cracked pepper, to taste then dig in. Enjoy!
