Prepare the egg: Crack the egg into a small fine-mesh sieve placed over a small bowl or a teacup. Gently swirl the sieve to drain away the thinner parts of the egg white (this is what makes the egg white wispy) - you can discard the liquid. Transfer the egg to a small bowl.
Bring a small pot of water to a gentle simmer (you should have at least 2 inches (5cm) of water in the pot), don't salt the water. You want the water to just gently simmer - you should see a couple of small bubbles on the surface, but the water can't boil rapidly!
Poach the Egg: Carefully transfer the drained egg from the bowl into the barely simmering water. Let it cook for around 4 minutes (3 to 3 1/2 minutes for a very runny yolk and 4 minutes for a moderately runny yolk).
Remove and Serve: Use a slotted spoon to carefully lift the poached egg from the water. Place it on a paper towel briefly to absorb any excess water, then serve immediately.
Enjoy!
