I'd like to give this a try, at the moment I'm half-way through reading this topic over the last week and half. To keep things simple, I'd like to try the recipe on the first page, before going to sourdough versions. I have good control of temperature. Questions:
1. If I wish to bake same-day as mixing the final dough, correct that:
a) 6 hours ball time, at 70F/21C
b) autolyse the additional flour/water before mixing in biga
2. Is it possible to use other metrics to gauge fermentation? I'm used to a spyglass/doughlette with sourdough, with a target to bake 60-100% rise. Based on what I read in this topic thus far, the biga doesn't really rise, maybe one could measure the pH? Then, once mixed, I wonder whether measuring rise of the final dough would be useful? This is mostly to try and create a correlation in my head and better understand what's going on.
3. What are target diameters for 250g and 280g dough ball?
I am somewhat impulsive and want to bake tomorrow, hence skipping the fridge. The plan is to use whole farts' 0365 brand organic bread flour for the biga, which is non-malted, and the only strong flour I have access to at the moment - no clue on the W value, but, I know it can take a pretty high hydration from past experiments. It's either this, or Anna Napoletana 00 flour (which is strong but becomes very stretchy/lax with no spring back and I think has a W of 270-280 if research is correct). Final flour will be grocery store brand that's also unmalted, lower protein in 10% range. I will consider purchasing the nuovolo super later, looks like fun; there's a specialty store in Los Angeles that sells it in small quantity, also central milling high gluten flour.
