In January I started my first batch of sourdough starter. The taste evolves weekly and is delicious. Within the last month I've noticed that after kneeding, the bread seems to get very sticky and rises so fast I can't keep up with it. I've tried adding more flour before and after the kneed, but it seems to suck in the moisture from the air or something and just gets stickier. It rises so fast that I punch down and let it rise about 3 times, which actually seems to develop the flavor more but also makes it difficult to manage. My last problem is that it doesn't seem to rise in the oven. I score the loaf just before putting it in and when I pull it out it doesn't even look as though it's been scored. Any thoughts or suggestions on any of these oddities?
