Peanut butter is a creamy spread that is made from roasted and ground peanuts.
Peanut butter is a vital component (along with bread and jelly) of a PB&J, or peanut butter and jelly sandwich. Whether smooth or crunchy, peanut butter is a delicious and useful ingredient in both sweet and savory dishes. Its history can be traced back to ancient Aztec and Inca civilizations, but the original patent for making peanut butter went to a Canadian chemist in 1884. The name peanut butter dates from around the same time, from its butter-like smoothness.
