Deep Avocado History
Scientists trace that the first known human consumption of avocadoes to archeological sites in the Puebla State of Mexico dating back to approximately 8000-7000 B.C.
Spanish conquistadores confronted avocados early in their conquests of Mexico and Central and South America. Fernando de Oviedo (1478-1557) describes avocados he encountered along the coast of Columbia:
“In the center of the fruit is a seed like a peeled chestnut. And between this and the rind is the part which is eaten, which is abundant, and is a paste similar to butter and of very good taste.
European sailors called avocados midshipman’s butter because they liked to spread it on their hardtack biscuits.
