I am a cook/ pastry chef and have been having major problems with my sourdough bread! I have been trying out different sourdough recipes and making my own starters and they just don't seem to be working. I get the dough mixed and let it rest then start the first period and it rises. I continue to knead it then shape the dough into rounds and let it proof for a second time which it does nothing but rise a hair. Then it goes into the oven at 425 for 10 min with steam and 30 with dry heat! The crust turns out crunchy but really hard and the inside is not airated at all. It is super dense and does not cook all the way! I am having the hardest time with this and have no idea what to do next! Help please!
