On another board we did a swap where each of us did a different kind of milk as all of the liquid. Some used powdered, some canned, some fresh. We all used the same recipe and there was even a control bar where water was used. The results were that no one could tell a difference! Some colored slightly, some were pure white but those were the noticable differences. It didn't matter what kind of milk was used, they all produced creamy lather. I just thought you'd all like to know the results of this!
