I feel like my starter is active, but my dough is not rising at all. As you can see in this picture, the dough just turns into a puddle on the baking pan after proofing for 16 hours. Also attached is a picture of the starter. It has bubbles, but maybe it is not active enough. It quickly develops a liquid layer on the top. I have tried using a light bulb in a cabinet to hold the temperature at 70-80 deg F. But, the dough turned out the same way before and after. I grew this starter from scratch over a period of 6 days. Can anybody tell what I am doing wrong?
Based on browsing of other posts, I think I will just try feeding the starter for another 5-10 days. Maybe it will become more active.
