Hi Liz! Generally when a crust is too tough, it means the dough has over baked or over-steamed in the oven. This can be due to too much water being poured into the pan when manually steaming the oven or if the dough is left in a covered vessel baking too long and the steam has nowhere to escape too. If neither of these sound like possibilities, give our baker's hotline a call at 855-371-2253 for further assistance. Happy baking!
