Is mashed unpeeled potatoes heterogeneous or homogeneous?

Mashed unpeeled potatoes are considered heterogeneous because they contain various components, including potato flesh, skin, and any added ingredients like butter or milk, which can be distinguished from one another. The mixture does not have a uniform composition throughout, as different textures and colors can be observed. This contrasts with a homogeneous mixture, where the components are evenly distributed and indistinguishable.
