Turbinado sugar is commonly sold as Sugar in the Raw. Demerara sugar, sanding sugar, or another coarse sugar can be substituted. Make sure the cookie dough is well chilled and firm so that it can be uniformly sliced. After the dough has been wrapped in parchment, it can be double-wrapped in plastic and frozen for up to 2 weeks.
