Overview

Cowpea (Vigna unguiculata) is a legume species native to West Africa, cultivated across tropical and subtropical regions for its edible seeds and pods. The seeds are small, kidney-shaped, and range in color from cream to brown to black, with a mild, earthy flavor and a creamy texture when cooked.

Origin and history

Cowpea is believed to have been domesticated in West Africa, with archaeological evidence dating its cultivation to at least 2000 BCE [1]. It spread to Asia and the Americas through trade and colonial routes, becoming a staple in many cuisines. In the Yucatán Peninsula, a local variety known as x’pelón has been cultivated by Maya communities for centuries, eaten fresh rather than dried [2]. The species includes four subspecies, three of which are cultivated: the common cowpea (subsp. unguiculata), catjang (subsp. cylindrica), and yardlong bean (subsp. sesquipedalis) [1].

Varieties and aliases

  • Common cowpea (Vigna unguiculata subsp. unguiculata) — the most widely grown type, used for dried seeds
  • Catjang (Vigna unguiculata subsp. cylindrica) — cultivated in South and Southeast Asia, smaller seeds
  • Yardlong bean (Vigna unguiculata subsp. sesquipedalis) — grown for its long, edible pods
  • X’pelón — Yucatec Maya name for a fresh-eating cowpea variety [2]
  • Black-eyed pea — a common name for a cream-colored variety with a black hilum
  • Southern pea — regional name in the southern United States

Culinary uses

Cowpea seeds are typically boiled or pressure-cooked and used in soups, stews, and salads. In West Africa, they are the base of dishes like akara (deep-fried bean fritters) and moi moi (steamed bean pudding). In the southern United States, black-eyed peas are a traditional New Year’s dish often cooked with pork and greens. Yardlong beans are stir-fried or steamed, common in Chinese and Southeast Asian cuisines. In Yucatán, x’pelón is eaten fresh, often added to salads or lightly cooked [2].

Cross-cuisine context

In the broader LA-relevant cuisines, cowpea appears as x’pelón in Yucatán, and yardlong beans are a staple in Chinese and Vietnamese stir-fries. Dried cowpea is used as a pulse in various preparations.
