A smaller variety of peanut compared to others, Spanish peanuts are known for their red skins and nutty flavor profile. They have a slightly higher oil content, which adds to their flavor when roasted. These peanuts are almost exclusively grown out West, in Texas, Oklahoma and New Mexico. Spanish peanuts are typically used in candy, confections, and peanut butter, and most of the organic peanuts produced in the U.S. are of the Spanish variety.
