I started to make a sourdough starter several days ago an I am puzzled at what is happening.
The starter was part bread flour and part rye flour (w/ water). I let it work for 24 hours before feeding part of the starter with all bread flour (and water). I then did feedings every 12 hours for a day or two and was quite pleased to see active fermentation going on at that time (the mass had doubled in volume). However, 12 hours after feeding the active starter I was faced with a lump that showed to activity. I let it set another 12 hours, after which there was still no activity. I decided to add a bit of rye flower at the next feeding but there is still no activity.
What is going on? What should I try next?
Thanks in advance.
