2 cups all-purpose flour
6 tablespoons granulated white sugar
1 teaspoon baking powder
1/2 teaspoon kosher salt
1/4 teaspoon baking soda
1 teaspoon orange zest (from 1 orange)
1 stick (8 tablespoons) unsalted butter, frozen solid
1/2 cup semi-sweet chocolate chips
1/2 cup sour cream
1 large egg
2 teaspoons turminado sugar
Adjust an oven rack to the lower-middle positition and preheat the oven to 400F. Line a baking sheet with parchment or nonstick liner.
Mix the flour, 6 tablespoons of the sugar, the baking powder, salt, baking soda, and orange zest in a medium bowl. Grate one-third of the butter into the flour mixture on the large holes of a box grater; toss to coat with the flour. Repeat grating and tossing twice more. Using your fingertips, work the butter and flour together a bit more. Mix in the chocolate chips.
Mix the sour cream and egg with a fork until smooth. Stir the sour cream mixture into the dry ingredients with the fork until large dough clumps form. Use your hands to press the dough against the side of the bowl to form a ball. (There may not seem to be enough liquid at first, but as you press, the dough will come together. If necessary, flick a little water into the bottom of the bowl to get the last bits to adhere.) Turn out onto a lightly floured work surface and pat into a 7 1/2-inch round about 3/4 inch thick. Sprinkle with the turminado sugar. Use a sharp knife to cut into 8 wedges. Place the wedges about 1 inch apart on the baking sheet. Bake until golden, 15 to 17 minutes. Serve hot, warm, or at room temperature.
