If using dried figs, soak in warm water until plump, then strain and chop into pieces. Discard the tough stems.
In a large bowl, combine the flour, sugar, cardamom, baking powder, salt, and orange zest. Cube or shred the frozen butter into the bowl, then use a pastry cutter to blend the flour mixture until crumbly.
Fold chopped walnuts or pecans into the flour mixture until evenly coated. Next, fold in the chopped figs.
In a small bowl, whisk buttermilk, orange juice, vanilla, and egg. Make a well in the center of the flour mixture then pour the wet ingredients into the well.
Use a fork to gradually incorporate the wet ingredients into the dry ingredients. Don't overwork the dough. If the dough still has crumbly, dry dough, add 1 tablespoon of buttermilk at a time until you have a shaggy dough.
Transfer the dough onto a lightly floured surface, and gently shape into an 8" disc. Divide dough into 8 to 12 wedges using a bench scraper. If using fresh figs, you can press a fig slice into each wedge.
Transfer scones to a parchment-lined baking sheet. Leave plenty of room in between the scones, as they will expand. Brush scones with half and half. Optionally, sprinkle with sugar. Bake for 20 minutes, or until the scones are golden brown.
Cool scones on a wire rack while you make the glaze.
Prepare Glaze
Whisk powdered sugar, vanilla extract, orange juice, and zest until smooth in consistency. Drizzle over cooled scones, and enjoy!
Notes
If using frozen figs, defrost first, then strain the excess liquid.
Folding the pecans and figs into the flour mixture keeps them from sinking to the bottom of the scones.
If the dough sticks to the bench scraper, dip the scraper into flour.It's also helpful to slide the scraper out when slicing the scones instead of lifting it up.
Scones are best when freshly baked. For this reason, I like to bake only the amount I will be eating (or serving) and freezing the rest for another time.
To freeze, slice the disc into wedges and wrap each wedge individually in foil then store in freezer bags.
You don't need to defrost frozen scones before baking them.
Scones can be stored in ziplock bags or an airtight container for 2 to 3 days.
