This Christmas I was given some heavy duty loaf pans, sized 9X5X2.5. This is larger than what is called for in the bread recipes I have. The loaves I have made in these new pans seem tall enough. So my question is, should I increase my recipes by 20% to help fill the pans so they can rise more up rather than from side to side and end to end? If I did my math correctly, these new pans have a 20% greater volume than do the pans called for in the recipes.
