NMNF Puzzle
Da Brownman's instructions for building a starter contain this instruction:
The starter should double 4 hours after the 2nd feeding. If it doesn't then toss the 2nd feeding total amount by weight and redo it.
I don't understand what this accomplishes. If I have 70gm of starter at the second feeding but it doesn't double, what is the advantage of throwing out 35 gram and adding new flour and water?
I'm sure there is a reason, but my old brain can't quite grasp it. I'd welcome any clarification. Thanks,
Greg
