But how is it to be eaten? … A few simple rules are so necessary for the proper enjoyment of this delicacy… In the first place, it is a rich article, and should be eaten with meals in preference to any other time, and always with bread and butter or delicate crackers… Eat it with a spoon or fork, using salt and pepper, and sometimes lime-juice is thought to be an agreeable addition. The avocádo is most frequently eaten in the above way, and when served with thin slices of bread and butter makes a delicious supplementary course for either breakfast or dinner. To try another method, pour over the pulp, just before eating, a spoonful of sherry wine; add a little sugar, a slight grating of nutmeg, if desired; serve with the invariable accompaniments of bread and butter or crackers.
