You can make as many eggs as you need. Use a pot size such that will give you at least 3 inches of surface area per egg so they don't stick together.
Fill your pot or sautee pan with 3 inches of water and bring to a boil; lower temperature slightly until it slows to a vigorous simmer (do not use a rolling boil which might break the yolks). There are many cooks who recommend adding bit of white vinegar to the water at this point to help the egg whites firm up, but if you are using fresh eggs you can skip this step. I did not use any vinegar.
Crack one egg into a small saucer or shallow cup. When your water is at a vigorous simmer, stir it several times in a clockwise circle with a slotted spoon. Gently lower the saucer or cup as close to the surface of the water as possible and slide the egg into the swirling water. Stirring in this way creates a little vortex which will spin the egg and help the white to form into a circle. Crack your second egg into the saucer or cup, then gently stir water again and lower your second egg into the water in the same manner. Cook for 3 minutes for "juicy" yolks, up to 2 additional minutes for a more firm yolk.
When the eggs are finished to your liking, remove one at a time from the simmering water with your slotted spoon. Allow excess water to drain off of the egg. Serve over a piece of toast.
Julia Childs says that you can make these ahead and hold for up to one day in ice water. To reheat, lower each egg into simmering water for 30 seconds, then serve.
