Crack an egg into a small bowl.
Bring water with vinegar to a high simmer/low boil.
Rapidly stir in circles (don't burn yourself!) to create a vortex in the water.
Gently pour egg from bowl into the centre of the vortex.
(I forgot to take a middle picture!) Let the egg sit in the water. Do not stir it or shift it. The water will keep it together. Remove after 3 minutes/ at desired doneness.
(Optional) Drain on paper towel.
Soft cooked is best cooked.
