Hello, there should be no problem with your approach. The method is to steam the sweet potato, then cool it and mash it, then add a small amount of cassava powder to make it alive, knead it into a ball and cook it in boiling water. The strong taste of sweet potato means that your cassava flour is not enough, or the cassava flour is impure, which leads to the taste of sweet potato masking cassava flour, while the light color indicates the problem of collocation. There are too many things in the flour, which is caused by too much flour or cassava flour. After personal analysis, I think there is something wrong with your cassava flour. I suggest replacing it. I hope it is useful to you, and I hope to adopt it ~
