Peanut butter is a food paste or spread made from ground, dry-roasted peanuts. It often contains additional ingredients that modify the taste or texture, such as salt, sweeteners, or emulsifiers. Peanut butter is popular in many countries. The United States is a leading exporter of peanut butter and itself consumes $800 million of peanut butter annually. Peanut butter is served as a spread on bread, toast, or crackers, and used to make sandwiches (notably the peanut butter and jelly sandwich). It is also used in a number of breakfast dishes and desserts, such as peanut-flavored granola, smoothies, crepes, cookies, brownies, or croissants. It is similar to other nut butters such as cashew butter and almond butter.
