Today poured most of my biga out of the quart bottle it was resting in, then added back equal parts flour and water, and a half t of sugar. Lid on, shake-shake-shake, then loosen the lid and set it aside at the back of the counter or in the fridge. If the lid is tight and the yeast works....... yes, it's possible that it will explode. So keep it loose.
Meanwhile, into the bowl with the biga went a cup of water and a cup of flour, plus a teas of yeast. With a little extra time, that should suffice. When the yeast is completely 'eaten' and still bubbling away, it loses the tame taste. The wild yeast overcomes it. Someday there will again be so much wild yeast in the air that I'll be able to set aside flour and water for a couple of days and it will bubble up. But it takes a lot of baking to get there, and I've only just begun.
I found durham flour recently - I love it. This bread will be all durham, and the crumb will have that distinctly golden durham wheat color. When it was working strongly I added a cup of home made yogurt, a T of oil, a heaping t of sugar, a slight t of salt, and enough flour to make a sticky, loose dough. I beat it with the kitchen aid for about 5 minutes, until it just began to ball on the paddle.
A dough this sticky is best kept off of the counter, in your hands as much as possible, and hands oiled, not floured. I tossed it around to finish it, kneading it a bit on the counter, picking it up and slapping it down to make the gluten structure strong. Oiled bowl, plastic wrap top, into the oven with only the light left on for warmth.
An hour later it was doubled, and, hands oiled I deflated it by pulling it away from the edges of the bowl, and broke it in two.
working it in my hands, I kneaded it into a ball, and placed it in a well-oiled pan, then did the same with the other piece.
I tried to snip the top of one, but the cut seemed like it might deflate the structure, so I gave up, didn't finish. Pressed course salt gently over the top (remember, hardly any salt in the bread itself), covered with plastic wrap and into the oven, out of drafts, to rise.
Properly risen, oven heated to 420, I placed the loaves in the oven then dashed a quarter cup of water onto the oven floor and closed the door to contain the steam. 3 minutes later, I repeated the steam bath. (Steam during the first 10 minutes keeps the surface moist and prevents the crust from hardening before the loaf rises). 7 minutes after that, I lowered the oven to 350 and left it for 40 minutes. Getting nicely brown, but the bread still stuck to the pans (usually a sign that the loaf is not yet done), so I returned it to the oven for another five, then prized the loaves gently from their pans and let them rest on the racks to finish the crust and finish setting the internal structure. When the bottoms tapped hollow, they came out to finish cooling on a rack.
As desired, the grain is large with many evenly distributed bubbles, and a definate 'chewiness.' Crisp crust and a chewy crumb! Yummmmmm
