I've made two banna breads Both times the sides were really crusty.First time I used my faveroite loaf pan, thicker metal. This time I used a thin cheapo loaf pan,paper lined. Still real crusty sides. Sure makes slicing difficult. It was still slightly warm. It says to rest in pan 10 minutes after removing fron oven. Do you think this is the problem. I reduced baking time by 5 minutes, didn't help.
