To poach the eggs, fill a wide sauté pan halfway with water. (A pan like
this is ideal.) Add vinegar and bring water to a brisk simmer, then reduce heat so the water is virtually still. Crack each egg into a small bowl and tip carefully into the water, submerging the bowl a bit as you pour. I like to add the eggs in a clockwise circle starting near the handle so I remember in which order to remove them for even cooking. Cook undisturbed for four minutes, until whites are set and yolks are runny. Remove eggs from pan with a strainer spoon (something like
this). Gently place eggs on a paper towel-lined plate and dab the tops to remove excess water. Cut away any scraggly whites if you like.
