so I need help!! I made the ciabatta recipe in the book BREAD the one w a biga. It turned out to have a crispy crust but so chewy it made our jaws hurt.I know it sounds conradictory. It rose well but the holes were not as good as i would have liked. I steam w a cast iron frying pan and spray after 3 times.after 15-20 min. I open the oven door slightly to get the steam out. I used bread flour as called for. Any ideas on why the jaw working chew????
