peanutbutter

Peanut butter is a paste made from ground roasted peanuts (Arachis hypogaea), a legume native to South America but now widely cultivated in tropical and subtropical regions worldwide, particularly in Africa, Asia, and North America. Despite the common name, peanuts are not true nuts but rather the seeds of a legume that develops underground after the flower stem is pushed into the soil.

The paste is characterized by a dense, spreadable texture with a rich, slightly sweet flavor and subtle earthiness. Commercial peanut butter typically contains roasted peanuts ground until the natural oils release, creating a smooth or chunky consistency depending on whether whole peanut pieces are retained. Most commercial varieties include added salt, sugar, and hydrogenated vegetable oil for stability and palatability, though natural peanut butters contain only peanuts and minimal salt.

Peanut butter serves as both a condiment and ingredient across numerous cuisines. In North American cooking, it is primarily consumed as a spread on bread, crackers, and fruit, and as a component in sandwiches, particularly paired with jelly or jam. In Asian cuisines—particularly Southeast Asian and West African traditions—peanut butter or ground peanut paste forms the foundation of satay sauces, curries, and dipping preparations that balance savory, sweet, and spicy elements.

Peanut butter is also incorporated into baked goods (cookies, brownies, energy bars), desserts, smoothies, and sauces for noodles and vegetable dishes. Its emulsifying properties and protein content make it valuable in both sweet and savory applications, and it can function as a binder in meat-based preparations. The ingredient pairs well with fruit, chocolate, jams, chili peppers, lime juice, and soy sauce.
