Okpa (pronounced Ọkpa) is a dish prepared by the Igbo people with a type of beans known as Bambara nuts.[1][2][3] It is common in Enugu state and classified as a traditional Nigerian delicacy. It is not exclusively eaten by the Igbo, nor is it universal among the Igbo (most-characteristic of Enugu State); other ethnic groups often eat it (with pap or by itself), and it may be that this is most-common (outside Igboland) in Niger State.[4][5] Other Igbo names for okpa include ịgba and ntucha. In Hausa, it is known as gurjiya or kwaruru.[6]
The main ingredients in okpa are Bambara nut flour, pepper, palm oil and (a modest amount of) seasoning. [7][8] Nutritionally, okpa has approximately 16.92% crude protein, 4.93% fat, 26.62% carbohydrate and 216.28 kcal energy value,[9] making it one of the most balanced staples.[10]
