.... I think, for the purposes of a person new to fermenting, it's most important to understand the interplay of the different factors. Properly sanitizing everything, having the right amount of headspace, fermenting in a vessel with a lid that actually seals, and working out how to vent CO2 without letting air in are all highly important. I see salt and starter as sort of a seesaw scenario (points to me for alliteration): one slows growth of undesirable microbes, and the other speeds growth of desirable microbes. When you get to the point that you have a handle on the other factors, you can play around with decreasing the salt and even the starter because it simply isn't as necessary. The next step for me will be playing with temperature. ......... cooler temperatures and cooler temperaments win the day. If patience and a fridge make for the best bread, I can't help wondering if a really long, slow ferment at maybe 70-74 degrees would be good. I welcome any thoughts from you or the community on this one.
