In small bowl, whisk flour, sugar, baking powder, nutmeg, and salt together. Stir in the grated orange rind. Cut in the cold butter using a small pastry cutter. Stir in the milk and incorporate ingredients to make a shaggy dough. Do not overwork dough. If making separate individual cobblers, divide the dough into four and flatten each piece slightly and place on top of plum base in each dish. Topping does not have to completely cover the plums. If making cobbler in one dish, divide the dough into four equal portions and flatten each portion into a circle and place on top of plum base. Sprinkle turbinado or granulated sugar over cobbler topping.
