Mix in the flour, cinnamon and chips. The dough will be pretty darn sticky. Carefully dump it onto a parchment- lined baking sheet and shape it into a 14x2-inch log (it helps if you wet your hands a little bit.) I studded a few extra cinnamon chips in the top of the log (so that the finished biscotti would yield a few that would be visible on top). Stick that log in the oven for the 1st bake.
Here's the baked log. Don't worry about the cracks- they're supposed to be there.
