Scones can be flavored in any of a number of ways, both sweet and savory. Give one or more of these ideas a try (flavorings are measured for 1 batch of scones), then riff on your own:
Currant scones: Add 11/2 cups dried currants. Consider soaking them in a little fruit juice or liquor before adding to the dough for a little extra flavor (Grand Marnier is wonderful).
Chocolate chip scones: Add 12/3 cups chocolate chips: Fold in semisweet or bittersweet chocolate chips, perhaps with some nuts or a little orange zest.
Ginger scones: Add 2 tablespoons grated ginger to give them a nice tang.
Jalapeño-cheddar: Roast, peel, seed and chop 2 jalapeños (or more), and add them to the dry ingredients along with 1 cup of grated cheddar cheese. Omit the sugar topping for savory scones.
Chive-Parmesan: Add 1/2 cup of chopped fresh chives to the dry ingredients along with 1 cup of grated Parmesan. Form the scones, then sprinkle a little more cheese over right before baking.
Prosciutto-Swiss: Chop 4 ounces sliced prosciutto and add to the dry ingredients along with 1 cup of grated Swiss cheese.
