I don't think of this article as a 'from scratch', given that there's recognisable prefab parts in it, but at the same time, that doesn't diminish its worth. Perhaps put another way: prefab keys can only be keys; cakemix can only become cake; sheet aluminium could become anything; milled flour could become anything. 'From scratch' is making something from generic materials, to me.
