In a small bowl whisk together 1/4 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°F for 15 to 18 minutes, or until they are golden.
