African yam bean — the high-protein 'stubborn bean' of southeastern Nigeria. Takes 3-5 hours to cook (or 45 min in pressure cooker), but delivers protein comparable to soybeans at a fraction of the cost.
For Igbo and Yoruba diaspora, yam bean porridge (ewa aganyin is a different bean but similar concept) is the breakfast food of home — the porridge that was already cooking when you woke up, served with palm oil and pepper. The long cooking time is a commitment — those who make it for you have given you hours.
African yam bean's protein content (22-25g/100g dry) is comparable to soybeans and significantly exceeds common beans, chickpeas, and black-eyed peas. The iron content (8.3mg/100g dry) is exceptional — the highest of commonly consumed West African legumes. For Black American women with iron deficiency (prevalence 3x white women), African yam bean provides heme-comparable iron delivery in a plant food. The high fiber content (both soluble and insoluble) provides prebiotic benefit and cholesterol-lowering activity. The protein quality is high — essential amino acid profile approaches meat equivalence when combined with grains.
Soak dried yam beans 6-8 hours (reduces cooking time and some gas-producing compounds). Boil 3-5 hours on stovetop (best flavor) or 40-50 min in pressure cooker. Season with palm oil, onion, crayfish, scotch bonnet, and salt for classic yam bean porridge. Do not add salt until almost cooked — salt hardening of the skin is the primary reason for very long cooking.
