I’m trying to revive a 15yr old dried sourdough starter a friend has given to me. I’m on my second attempt now, and I don’t really know what I’m doing wrong.
I’ve followed the instructions, and added 1/3 cup flour and a bit over 1/2 cup water to my bubbly starter. However, the starter didn’t rise at all during the day. It still has bubbles in it. I thought I might have made the starter too wet, resulting in gas floating to the top rather then trapping it in the starter, so I’ve added two tablespoons of APF to create a thick batter like consistency. I’ve only added the extra flour just then, so I don’t know the outcome yet.There’s bubbles currently present in the starter.
I’m not sure how I go from here though. Do I discard half of the starter and keep feeding it 1/3c flour and 1/2c water daily? Do I stir it twice daily and stop feeding it? Do I feed it daily and stir twice daily? Do I feed it twice daily? I’ve used water from the tap, which hasn’t been an issue in previous starters.
I hope you can help me out! I’ve got a little bit of dried starter still there, but I don’t want to waste a 15yr old starter!
