When rounding the dough and shaping the rolls, it is important to keep the remaining dough covered, otherwise it will quickly dry out and develop a skin. Rolling the dough into symmetrical rounds takes a little practice, but you will quickly get the hang of it. A dry, unfloured work surface helps because the dough will stick a little. Although we like using a French-style rolling pin for flattening the rolls, a more traditional option is a thin dowel or the handle of a wooden spoon. Whatever your choice, lightly flour it or the dough will stick to it.
