Can anyone help me. I have been baking plain sourdough bread for about a year, now. I had great success with the no-knead recipes, but have decided to try some other recipes. When I tried to bake a sandwich loaf, the crust got very thick and hard. I decided to put the loaf pan and all, into my cast iron dutch oven and cook as I used to cook the no-knead. I set the temperature for 450, preheated the oven and dutch oven, popped the bread in it and set the timer for 30 minutes. At that time, I inserted a thermometer into the bread, and left it for a further 15 minutes. The internal temperature came up to 192 degrees, and never went above that, even though I left it in for another 30 minutes. Any comments or suggestions?
I'm not sure why you wanted an internal temp above 190F for a sandwich loaf. Did your recipe call for a higher temp? Was it a specific recipe for sandwich type loaf? At what temp did you bake the loaf? The hard crust may have been caused by baking it in too hot an oven.
Sandwich bread also has additional ingredients, such as egg, buttermilk or plain milk, and butter, and those enrichments will result in a much softer crust.
