Peanuts (Technically a Legume)

What it is

The seeds of a legume that ripens underground (hence "groundnut") — not a tree nut at all, despite the name. Sold in-shell, shelled (raw or roasted), as peanut butter, and as oil. A major allergen.

How it's made

The plant's pods develop underground; dug up, dried, and roasted or boiled. Roasting develops their familiar flavor; boiling (in-shell, in salty water) is a distinct Southern US and West African preparation giving a soft, savory, bean-like result. Ground into peanut butter or sauce-thickening paste; pressed for peanut oil.

Flavor profile

Roasted: rich, nutty, savory, sweet. Raw/boiled: beanier, softer, "green." Ground: the familiar creamy, savory richness. High in protein and fat, with a robust flavor that anchors sauces.

Culinary uses

A genuine four-continent ingredient. West/Central African: ground peanuts thicken rich stews — maafe/groundnut stew (peanut-and-tomato stew with meat), a cornerstone dish. Southeast Asian: ground roasted peanuts make satay sauce and dress gado-gado and noodle dishes; whole peanuts garnish pad thai. Chinese (esp. Sichuan/Hunan): stir-fried into kung pao chicken, ground into sauces, fried as a snack. American South: boiled peanuts (a roadside tradition), peanut brittle, and the peanut's deep tie to Southern agriculture (and George Washington Carver). Peanut butter is a global pantry staple. Toasting/grinding for sauces is the defining cooking technique.

Regional variations

West Africa (Senegal, Nigeria, Ghana): maafe/groundnut stew. Southeast Asia (Indonesia, Thailand, Malaysia, Vietnam): satay sauce, gado-gado, pad thai. China: kung pao and fried peanut snacks. American South: boiled peanuts, peanut pie, and peanut farming heritage. South America (the origin): native and used in Andean and Peruvian sauces (ocopa, carapulcra).

Cultural & historical context

Peanuts are native to South America, domesticated thousands of years ago, then carried by Portuguese and Spanish traders to Africa and Asia, where they were so enthusiastically adopted that groundnut stews and satay feel utterly indigenous. In the American South, peanuts (brought via the African diaspora) reshaped agriculture after cotton. The botanical "legume, not nut" fact matters practically for understanding why they cook and thicken like beans — and is critical for allergy labeling.
