Thanks Frozzie for all that info. When you say different blends, do you mean different flours with wheat (buckwheat, spelt etc) or different grades of wheat flour, gluten content etc?
I wonder what the bakers would think of me, a suburban chick with a fancy blender, trying to make anything remotely baguette-like, compared with centuries of tradition and experience. But it's fun hey!
I did like the varoma steaming method in another post, Tenina's? and will attempt the techniques you've explained here to form the loaf.
