In a small (1-2 qt) saucepan, simmer the currants and whiskey over low heat until the liquid evaporates, about 25-35 minutes. Remove from the heat and let cool to room temperature.
Line a baking sheet with parchment paper and set aside. Prepare a lightly floured work surface with a small mound of flour along the side for dusting your hands later.
Using a food processor fitted with the S-blade, a stand mixer fitted with the paddle attachment, or a large bowl and your hands, combine all the dry ingredients. Pulse, mix on low, or stir to blend together.
Add the butter and pulse 3-5 times or mix on low to distribute the butter into the dry ingredients. The mixture should become pale yellow and have the consistency of fine meal with small bits of butter.
Add the cream, honey, and vanilla extract to the small saucepan of cooled whiskey currants. Whisk to combine.
If using a food processor, transfer the flour-butter mixture to a large bowl, otherwise proceed with the bowl you already are using. Make a well in the center of the dry ingredients and pour the wet currant mix into the well. Using one hand, gently fold in the dry ingredients, mixing until just combined. The dough will be crumbly.
Carefully turn the dough out onto your prepared work surface and dust your hands with the flour you set aside for that purpose. Gently knead the dough a few times to bring all the crumbly pieces together into a ball.
Roll or pat the dough out into a 12-inch log. Using the palms of your hand, flatten the log into a rectangle about 4 inches wide and 10-12 inches long. It should be about ¾-inch thick.
Cut the dough log lengthwise into 1 ½-inch-wide strips. You should have 7-8 pieces and you may need to press together the pieces from the two ends depending on how precise your starting rectangle was.
Place the pieces 1 inch apart on the parchment-lined sheet. Flatten each piece at one end with one palm while cupping the other end to stabilize it and form rounded corners. Repeat for the other side of the piece. You should have oval-like pieces about ½ inch thick and 4 ½-5 inches long.
Freeze on the baking sheet for 1 hour. (If freezing for later, transfer to a freezer-safe container after they've been frozen and store up to 3 months.)
Preheat the oven to 350 degrees with the rack in the upper middle position. Combine the sugar and cinnamon in a small bowl.
Once the oven is preheated, remove the dough paddles from the freezer. If you want smaller scones, cut the paddles in half at this point. Brush each paddle with a thin layer of cream then sprinkle with an even layer of the cinnamon sugar topping.
Bake immediately for 17-30 minutes (17-19 minutes for half size, 28-30 minutes for the large size). The scones will be nicely browned on top and along the edges. Let rest on the baking sheet for 5 minutes, otherwise they will fall apart when you try to move them. Serve.
