I would agree, the branching pattern, bi-pinnate leaves and bark are all saying ash. It is a hardwood (obviously) and not toxic, that is to say, there are no toxins in an ash tree. I have no idea what the flavor profile will be. It will light fast and burn fast, as the tree is a fast grower, with an overall less dense structure.
