Prepare a poached egg. Carefully break the egg, strain the watery white through a strainer. Next, boil the water, add a couple of drops of vinegar, turn on the gas so that the water does not boil. Form a "funnel" of water and carefully lower the egg into it, bringing it as close to the funnel as possible. Cook for 3.5 minutes. Carefully remove with a slotted spoon.
