To make cinnamon rolls with your bread crusts, you'll want to be strategic with how you slice the crusts off of the bread. Cut each crust off in one long piece, turning the bread at each angle to follow it evenly. Then, working with one piece of crust at a time, roll it up into a pinwheel. Stick a toothpick through it to keep the crust intact. Then, melt a tablespoon of butter over medium heat until it's bubbly and clearly warmed up.
