There are many varieties of avocados, several of which are grown commercially. The Hass variety is the most popular commercially grown variety and has a deep, rich flavor. Avocados are ready to eat when they are slightly soft and yield to gentle pressure. The skin is peeled away and the flesh of the fruit is eaten. Avocados can be eaten by themselves or used for guacamole, sandwiches, salads, omelets, desserts and much more.
