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.
While the egg is cooking, toast a piece of bread in a toaster then slather it with butter and cut it into thin sticks (aka soldiers).
When the six minutes are up, run the saucepan and egg immediately under cold water until the egg is cool enough to be handled.
Using a butter knife, crack the top edge of the egg then gently slice the top bit of the egg off.
Place the egg in the soft egg dish and serve with the buttery toast soldiers and the egg top. Side Note: If you don't have the soft egg dish, you can peel the egg completely (carefully) and serve it in a ramekin.
