1. Preheat oven to 375°F. Place the flour, sugar, baking powder, and salt in a large mixing bowl and stir to combine. Add the butter and blend using a pastry blender or two butter knives. Add the cheese, milk, and egg and stir until the dough begins to come together, then add the pears.
2. Generously flour working surface and place the dough on top. Sprinkle the dough with flour and pat into a 7-inch circle. Cut circle into 6 wedges. Transfer wedges to a non-stick or parchment paper-lined baking sheet. Allow at least 2 inches between each scone. Bake until firm and golden, about 25 minutes. Transfer to a wire rack to cool before serving.
