From the kitchen of: Jean Herr, photography director. Every year we had Thanksgiving and Christmas at my grandmother's house in Berwick, Ohio, a suburb of Columbus. My mother's job was to bring her homemade rolls, pumpkin pies, and Twice-Baked Potatoes--my sister, Robin, and I used to help her with them. The holidays were the only time of year she baked them, and she would make tons so we could have them with leftover turkey for days. She used to joke that she got the recipe off a can of evaporated milk. Now our family can't get together for the holidays without someone making them.Prep: 20 minutes; Bake: 1 hour 30 minutes.
