Reduce the heat under the skillet
to moderately low so the water simmers. One at a time, break the eggs into a small bowl and pour them into the simmering water. Cook until the whites are just firm and the yolks are still runny, about 3 minutes. Using a slotted spoon, transfer the eggs to paper towels and gently blot dry. Put each egg in a small, warmed bowl. Serve immediately with the Parmesan and smoked salmon toasts.
