Sourdough bread rose to much in the oven
I successfully got a starter going after about two weeks of feeding I tried to make my first loaf of bread I kneaded it with a dough hook for about 10 minutes and put it aside to rise after about 45 minutes it had doubled in size. this surprised me because everything that I read said that without commercial yeast the rising time would be longer. I then knocked the dough down kneaded it and placed it into a bread pan and in about half an hour was an inch over the top so I heated the oven and put it in when I checked the bread 40 minutes later it had risen about 6in over the pan. Why did this happen and would rising the bread three times instead of two help to prevent it?
