Fonio

Fonio is an annual grass with slender, finger-like flower spikes that grows to about 30 to 80 cm. Its seeds are among the smallest of all cereals, only about 1 to 1.5 mm across, with a pale cream to yellow color when the hull is removed. Cooked fonio is light and fluffy, similar to couscous, with a delicate flavor that is faintly nutty and earthy. The grain is naturally gluten free. Because the grains are so small and tightly hulled, dehulling by hand was once very laborious, and mechanical hullers have made it more available. It is sold as whole grain, flour and in some places as a ready-to-cook product. A related species, black fonio (Digitaria iburua), is grown in a smaller area.

White fonio was domesticated in the West African savanna, probably more than 5,000 years ago, from a wild grass in the region, and is considered one of Africa's oldest crops. It grows today in dry areas of Guinea, Mali, Burkina Faso, Nigeria, Senegal and neighboring countries. The name fonio is of Wolof origin in Senegal, while other names such as acha in Nigeria and findi in Mande languages reflect its many local communities. The species name exilis is Latin for slender or thin, describing the grain and plant.

Fonio has fed West Africans for millennia. European explorers noted it in the Sahel region in later centuries. It has deep ceremonial roots in some groups, such as the Dogon of Mali, in whose traditions fonio is tied to the creation of the world, and in many communities it is served to chiefs and guests of honor or at festivals.

Its nickname hungry rice reflects its role as a quick crop: it ripens in as little as six to eight weeks and can be harvested during the lean season before other cereals are ready. It tolerates poor, sandy soils and drought, so it was valued as a reliable food in difficult conditions.

For much of the twentieth century fonio was overlooked in favor of imported rice and wheat, partly because of the effort of hulling. In recent decades, chefs and nutrition researchers have brought it fresh attention, and development projects have supported mechanical dehullers and smallholder farmers. Its profile as a gluten-free, climate-resilient grain has made it increasingly visible in specialty food markets in Europe and North America.

Fonio is steamed or boiled in a few minutes and eaten like couscous with stews, sauces and vegetables. It is cooked into porridge, shaped into balls, or added to salads and pilafs. In West Africa it is also used to brew beer and to make flatbreads and fritters. The flour can be mixed with other flours in baking. Cooking fonio quickly in lightly salted water, then steaming, keeps the grains separate. Straw from the plant is used as animal fodder, and the grain is part of traditional feasts and rituals.

Fonio is a whole grain eaten largely without added gluten, which makes it a useful choice for people avoiding wheat. It supplies carbohydrate and a little protein, and it is noted for amino acids such as methionine and cysteine, which are low in many other cereals. Nutrient values vary with processing and how thoroughly the grain is polished. Evidence on specific health effects is limited, so it is best viewed as a nutritious, versatile grain rather than a special remedy.
