Peanut butter, popular in many countries, is a food paste made primarily from ground dry roasted peanuts. Some varieties contain added salt, seed oils, emulsifiers, and sugar, whereas "natural" types of peanut butter consist solely of ground peanuts. It is mainly used as a sandwich spread, sometimes in combination with other spreads such as jam, honey, chocolate (in various forms), vegetables or cheese. The United States is a leading exporter of peanut butter and consumes $800 million worth annually. Nuts are also prepared comparably as nut butters.
