I am in the process of starting with my San Francisco Sourdough starter from Sourdough inc.
Stage 4 of their instructions say after feeding, disgard all but a little over one cup of culture or the jars will overflow. ( I am not worried about this )Then in italics it says " Discgarding dilutes rhe culture and reduces acid build up".
I don't understand how this could possibly dilute the mixture as the portion thrown away is exactly like the portion kept. If it was divided before the feeding and then fed, would not the same mixture be made if the thick pancake like mixture was reproduced?
Also it says after several of these 12 hour feedings I should see a 2 to 3 inch rise in my starter indicating it was reading to be used. How many 12 hour mixtures am I to expect plus or minus a few?
Thanks, I am really looking forward to the end result, and am enjoying the science along the way.
