sinensis said:i didn't want to waste the dough, so i gave it another chance. it got an extra day at 60°F, and it's looking better. now it's in the fridge. my guess is the taste will be a bit off, and it will be harder to work with (lower strength and elasticity). but i think i'll get some pizzas out of it.
idk, it's years old, but i haven't used it since the winter. when i know i'm not going to bake for a while, i feed it, wait a few hours (5?), transfer some to a ziplock bag, and fridge it.
it's been almost a week since i brought it out of the fridge, and i've been feeding it daily. for the first feeding, i kept it overnight in a 85-90°F box. idk what the ratio of old starter was, but there was for sure more flour and water than fridge starter in there. overall hydration something like 100%. so it's possible that right there a problem happened. maybe existing crap in the new flour took over. i tried to prevent this by keeping it at ~90°F. based on what i've read, this creates a good environment for lactobacilli and hopefully gets the pH down before other stuff can grow. but maybe it still failed.
and then subsequent feedings were once or twice per day. ratio of old starter to new flour+water was about 1:1 for each feeding.
i'm not sentimental over my starter. i don't mind pitching it and starting again. i have some dehydrated starter in a sealed packet from sourdo.com in the fridge.
I see I see. interesting. I need to get one of those fancy temperature control bread boxes. But my average air temperature is in the 80s year round. One of my problem this go around is that my air temperature is likely too high. Since the average air temp inside my house is about 83 degrees at the moment.
Your starter is a lot older than mine. When was the last time you fed the starter while it was in the refrigerator over winter?
