My mom's potato dough rolls are famous among our extended family and the subject of negotiation, requests, and even squabbling. The relatives insist she bring them to every holiday meal: "Is Sandy bringing her rolls?" is all they want to know. As soon as we arrive plates of rolls get squirreled away for cousins who haven't shown up yet, or for "later." And that's before the meal even starts. My mother, being a very kind and gracious cook, is not one to be secretive about her recipes. These rolls are an open secret — not hidden away but shared freely. They're perfectly easy to make, and this Thanksgiving, let me suggest that you do.
