I lost track of the hydration of this loaf. It is somewhere between 85 and 90%. Prefermented flour (KA ap and a touch of Bob's Red Mill light rye) and water was added to a 100% starter. The dough was "folded" three times at 45 minute intervals, then fermented in bulk for about another 2.5 hours at about 75 - 80 degrees. It was then poured out onto a bed of rice and wheat flour, "shaped" by folding on itself in thirds, and quickly moved to a floured couche, where it proofed for about 2.5 hours more. At this point, the dough was very delicate. It was very gently flipped onto a piece of parchment, loaded and baked at 500 degrees, the first 15 minutes under a stainless steel bowl. The finished loaf had a height of about an inch and a half. The crust was crispy and not too thick. The crumb was very translucent and springy, with a honeycomb effect that brought to mind the Japanese baguettes of which we have seen photos. The taste was mild, with a slight tang.
