To make a version of Panera’s orange scones, combine the ingredients for classic scones, and add orange zest to the mixture. Dip the baked scones in a glaze of sugar and orange juice. MyBakingAddiction.com offers a recipe that yields eight scones and takes half an hour to prepare.
First, preheat the oven to 400 degrees Fahrenheit, and line a baking sheet with parchment paper. In a bowl, use your fingertips to mix 1/3 cup of sugar with zest from 2 oranges until moist. Stir in 2 cups of all-purpose flour, 1 teaspoon of baking powder, 1/4 teaspoon of baking soda and 1/2 teaspoon of salt. Grate or cut 8 tablespoons of unsalted frozen butter into the mixture, and use your fingers to create a crumbly texture.
In another bowl, whisk together 1/2 cup of sour cream and 1 large egg, and pour it into the flour mixture. Press the dough into a ball. Flour a surface, and pat the ball into a circle 3/4 inch thick. Cut the circle into eight triangles, and place them on the baking sheet. Bake them for 10 minutes until golden.
For the glaze, combine 3 tablespoons of melted unsalted butter, 1 cup of confectioner's sugar, 1/2 teaspoon of pure vanilla extract and 2 tablespoons of freshly squeezed orange juice. Whisk the ingredients together until smooth. Dip the tops of the baked scones into the glaze, and let it harden before serving. Repeat the dipping for a thicker glaze.
