Where was peanutbutter invented at?

Peanut butter was first invented in the late 1800s in the United States. The earliest known reference to peanut butter dates back to 1895 when a patent was filed by John Harvey Kellogg for a "process of preparing nutmeal." Kellogg's method involved roasting peanuts, grinding them into a paste, and adding salt and sugar. In the early 1900s, peanut butter became a popular food item in the United States, and it was eventually mass-produced and sold commercially.
