Data from decentralized consumer trials of gari-eba, a sub-product of cassava (Manihot esculenta Crantz). Consumer testing was carried out in 2022 in Cameroon and Nigeria using the tricot approach. Diverse consumers in villages, towns and cities evaluated the overall acceptability of gari-eba made from 13 cassava genotypes. Apart from overall preference of the samples, the following traits were evaluated for eba based on the triangulated insights obtained by earlier survey and participatory work in the three areas. Nigeria (Osun and Benue States): colour, smoothness, mouldability, stretchability, and taste. Cameroon (Littoral zone): colour, odour, taste, firmness and stretchability. Traits in common are: colour, taste and stretchability.
