1 rounded teaspoon baking soda
2 rounded teaspoons cream of tartar
2 tablespoons sugar
1/2 teaspoon salt
1 stick plus 1 tablespoon cold butter
1 beaten egg
3/4 cup buttermilk
1/2 cup raspberries
1/2 cup blueberries
1/2 cup chopped strawberries
3 tablespoons melted butter
1/2 teaspoon lemon extract
1-2 tablespoons of milk, if needed to thin glaze
Refrigerate a metal bowl for 5 minutes to get it cold.
Preheat the oven to 425 degrees.
In the refrigerated bowl, add the flour, baking soda, cream of tartar, sugar and salt. Cut the cold butter into small cubes and add to the flour mixture. Using a pastry cutter, cut the butter in with the flour mixture until the butter is mostly mixed in. It is okay if there are small pieces of butter.
Make a well in the flour, in the center of the bowl. Add the egg and buttermilk to the well. Using a wooden spoon, mix the wet ingredients into the dry ingredients. Add the fruit and mix just until blended, being careful not to overmix.
Put about 1/2 cup of flour on the cupboard. Turn the dough out onto the floured counter. Turn it over so the floured side is up. Make a disk that is about 1 1/4 inches thick. Use a knife to cut the disk into 8 triangles, as if you were cutting a pie. Place the scones on a greased cookie sheet, or a nonstick baking mat.
Bake immediately for 12-14 minutes. Allow the scones to cool for 10 minutes and prepare the glaze.
In a small bowl, melt the 3 tablespoons of butter. Add in the powdered sugar and lemon . Mix well. If needed, add 1-2 tablespoons of milk in order to easily spoon the glaze over the scones.
Glaze the top of the scones. The glaze will run over the sides of the warm scones.
