Ancient Aztecs and Incas first to invent peanut butter

Did you know that the ancient Aztecs and Incas invented the extremely nutritious peanut butter, although it didn’t have its smooth texture back then?

They used to roast the nuts and mash them into a paste. Vegetable oil was added later and after  modern mixing machines were invented,  peanut butter got its smooth texture, like we know it today.

It is also said that George Washington was the first to invent modern peanut butter and that together with a businessman, they polularized the growing peanuts in the American South, as well as published recipes that included peanut butter.
