Fruit of Persea americana, of the laurel family, a tree native to the Western Hemisphere from Mexico south to the Andean regions. Avocados are extremely variable in shape, size, and colour (green to dark purple). The outer skin may be thin, or coarse and woody. The greenish or yellowish flesh has a buttery consistency and a rich, nutty flavour. In some varieties the flesh contains as much as 25% unsaturated oil. Avocados are the principal ingredient of the Mexican sauce guacamole. They provide thiamine, riboflavin, and vitamin A.
