Just made a sourdough version of these rolls using leftover mashed potatoes and they turned out great! How long do these rolls usually keep? And what is the best way to conserve them? Should I refrigerate or put them in a plastic bag at room temperature? Thanks! Bread that is made with a potato product of some sort tends to have a longer shelf life. The best way to keep them is in a plastic bag at room temperature. If you are in a humid climate, then you can refrigerate the rolls and reheat in the oven to serve. ~Amy
