Africa
Africa, particularly Nigeria and Ghana, is renowned for its rich variety of edible clays, deeply rooted in cultural and traditional practices. Among the most sought-after is African Kaolin Clay, known for its soft, powdery texture and clean, mildly tangy mineral taste. Eko Grey and Eko White clays, named after the Yoruba word for Lagos, are popular for their smooth crunch and slightly salty, earthy notes. Calabar chalk and Nzu, both widely consumed across West Africa, offer a dry, chalky bite with a distinctive clay-dust finish. Ulo, a term often used interchangeably for certain Nigerian slates and hard clays, comes in both chalky and slate-like (Ulo Slate) forms—valued for their dense, layered crunch and earthy, metallic aftertaste. These clays reflect the mineral-rich soils of the African continent and are celebrated for both their flavor and their deep cultural significance.
