In a small bowl whisk together 0.25 cup of the cream, the egg yolk, and the vanilla.
Mix the flour, 3 tablespoons of the sugar, the salt, the baking powder, the baking soda, and the cinnamon, add the butter until it resembles a coarse meal. Don’t overmix.
Stir in the nuts and dried fruit
Add the cream mixture with a fork until the mixture forms a sticky but manageable dough.
Knead the dough gently on a lightly floured surface for 30 seconds, pat it into a 3/4-inch-thick round, and cut it into 6 wedges.
Transfer the wedges to a lightly greased baking sheet (or parchment paper), brush them with the additional cream, and sprinkle them with the additional sugar.
Bake the scones at 400 for 15 to 18 minutes, or until they are golden.
