In a large bowl, whisk together the flour, sugar, baking powder, and salt. Cut the cold butter into the flour mixture with a pastry blender (or two forks) until the mixture resembles course crumbs.
In a seperate bowl, whisk together the half-and-half, almond extract, and the beaten egg. Pour half of the liquid into the flour mixture, stir until flour mixture is moistened, being careful not to overmix. Add the rasbberries and remaining liquid, carefully stirring just until incorporated.
Turn dough onto a lightly floured surface, carefully round into a slightly flattened disk. Using a bench scraper, cut the disk into 8 even wedges. Place onto parchment lined sheet tray and chill in refrigerator for 1 hour.
Preheat oven to 400°F. Lightly brush the top of each scone with egg wash or cream. Bake the scones for about 20 minutes, or until golden brown. Remove from oven and allow to cool completely.
