A bread baker's best friend is an instant thermometer. At least that is what I've told myself since I started baking bread. I haven't had an undercooked loaf since I started using one, and it's great for other food prep as well. Sometimes it's pretty tough to know if it's done, especially when you have a multi-grain or other additional ingredients beyond your standard white loaf.
Baking a few loaves for the week and the kitchen smells heavenly right before bed!
