I can't help myself. It just irks me to throw that much starter away. I know you must be shaking your head in disbelief - is she STILL on that stupid starter??? OK, I promise this will be the last . . .
I have decided to experiment. As I have said before, when I feed my starters, I deal in smaller quantities and I very seldom throw any of it away. So, as an experiment, I have decided to keep the portion of the starter that I would have normally thrown away today (are you still with me???) So now I will have two Tartine Starters. One I will continue to follow the instructions per Ms. Stewart - kept 75 tiny little grams of starter, throw the rest away and feed the tiny little 75 grams with 150 grams of the flour blend and 100 grams of luke warm water. Starter #2 will be MY experiment which I will feed it the way I normally feed my starters - each day it gets feed 4 T of the flour blend and 3 T of the luke warm water. Instead of covering the mason jar with a dish towel, I have placed a jar top on it with a hole punched to let the "gases" out.
At the end of the 15 to 20 days, I will bake two loaves of bread - one with the starter made per Ms. Stewart's instructions and one done my way. May the best baker win!!! If my theory proves me right, there really should not be any difference between the two breads (BUT if there is, I hope mine is better!)
