As I've mentioned, my daughter and I took a class to learn how to make sourdough bread. It's been over a year now and my daughter has gone absolutely crazy for sourdough! She has perfected her recipe and I've changed the ratio's on my sourdough recipe to reflect those changes.
I haven't made sourdough in several months - 4 or 5 - all the while my starter sat in my fridge. I have heard a million times that you can't kill your starter so I wasn't worried about it - until yesterday when I pulled it out of the fridge.
I poured it all out except for 50 grams. Then I fed it with 100 grams bread flour and 100 grams water. I let it sit overnight and when I woke up - there was absolutely NO PROGRESS!! Yikes!
I googled and researched and I came up with this: pour it all out except 50 grams. Then feed it with 50 grams bread flour and 50 grams warm water. A 1:1:1 ratio. It will take a few days of feeding with that ratio for it to come around again. It needs to be kept at a temperature between 70 - 78 degrees, so I put it in my oven with the oven light on.
Feed every 12 hours. Keep using the 1:1:1 ratio. Keep on counter - DO NOT PUT BACK IN THE FRIDGE.
SIGNS OF LIFE:
Bubbles throughout (not just on top)
A mild tangy or yeasty smell
Any rise at all, even 25 - 50%
