This is a perfectly cooked egg, with a delightfully runny yolk, that will slide cleanly off the pan, using no oil whatsoever. Detailed instructions regarding cook times and skillet temperatures are provided so you will no longer accidentially cook your egg too long and end up with a cooked yolk or a hard skin. Your non-stick skillet cannot be worn down or this will not work well. If it's worn down, you can use a non-stick spray, but the skin of the egg will not be as clean looking.
