Oaxaca [pronounced Wuh-HAH-kuh] cheese is a semi-soft white cowâs milk cheese from Mexico. It is named for the southern Mexican state of Oaxaca, where it originated from. Like mozzarella, Oaxaca cheese is produced using the pasta filata method of stretching the curd.
The earliest evidence of cheese-making in the archaeological record dates back to 5,500 BCE, in what is now Kujawy, Poland, where strainers with milk fats molecules have been found. Earliest proposed dates for the origin of cheesemaking range from around 8000 BCE, when sheep were first domesticated.
