Avocados
Avocados originated in southern Mexico and Central America, with archaeological evidence showing cultivation as early as 5000 BCE. The wild ancestor of the avocado (Persea americana) was first domesticated by Mesoamerican cultures such as the Olmecs and Mayans, who valued it for its rich, buttery flesh and high nutritional value.
The name “avocado” comes from the Nahuatl word ahuacatl, which means both “avocado” and “testicle”—a nod to the fruit’s shape and its symbolic role in fertility rituals. Spanish colonizers spread the fruit to the Caribbean and South America, and it eventually reached California in the 19th century, where the Hass variety was developed in the 1920s.
