Fake holidays can be rather tiresome (International Talk Like A Pirate Day, is that still even a thing?!) but Houstonians are always down for celebrating good food, especially a Tex-Mex staple like guacamole.

Whether you’re enjoying some of the city’s best guac at Escalante’s or breaking out the mortar and pestle to make your own in the comforts of home on National Guacamole Day—that’s September 16—here are some fun facts to ponder over in between those chip-and-dip bites. After all, as Texans, we already know how to make and/or find killer guac, so be prepared to pump up your Lone Star street cred by dropping some knowledge bombs over margs and chips. Talk about food for thought!

5 Fun Facts About Avocados and Guacamole

1. Avocados are native to central Mexico. It is believed that the first variation of guacamole was created by Aztec natives in the 16th Century. They called it ahuaca-mulli, or avocado-sauce, a simple name for a simple (yet delicious) snack.
2. Not only is guacamole delicious, but it is also good for you, as avocados are rich in monounsaturated fat. Avocados can also sometimes be eaten in place of other fatty ingredients, like butter. Good fat? Who would have thought guac would be so diet-friendly…
3. According to the Guinness Book of World Records, the largest serving of guacamole ever prepared weighed 5,885.24 lbs and was made by 450 students in Tancítaro, Mexico. I guess we know who to call for the next tailgate party!
4. Arguably the most popular variety of avocado used in guacamole is the Hass avocado, which was named for postmaster Rudolph Hass in 1935 after he planted a seed at his home. There has been some debate over the spelling of his avocado, but rest assured, it’s HASS, not HAAS (which is a common mistake!)
5. Although it’s common knowledge that avocados are fruit, they are specifically a “single-seeded berry” because of their thick skin and encased seed. So technically guacamole is a berry sauce. It might sound weird, but it doesn’t make it any less delectable.
