Efo riro is a Yoruba vegetable stew, and the name says exactly what it is: efo means vegetable or leafy green, riro means to stir or mix. Stirred greens.
The vegetables it is properly made with are specific. Efo shoko, known as Lagos spinach, and efo tete, African spinach, are the two local greens used in Nigeria, and they behave differently from the spinach sold in European supermarkets, firmer, with more structure, and they hold up to the cooking without collapsing. Outside Nigeria most people use whatever spinach they can get, which works, though the texture is softer.
What distinguishes efo riro from a simple pot of greens is the base it is stirred into. Blended red pepper and tomato are fried down in palm oil, with iru, locust bean, providing the deep savoury note, plus crayfish, assorted meat and often smoked or dried fish. The greens go in near the end and are stirred through rather than cooked down.
It is quick, which is unusual for a Nigerian soup, and it is low enough in carbohydrate that it is regularly eaten on its own rather than with swallow, one of the few in the repertoire where that is normal.
Versions are cooked in Ghana and Cameroon too, with small differences.
