Begin by poaching the figs. Add 1 cup of red wine and 1/2 cup of granulated sugar to a large sauté pan over medium heat. Let the mixture come to a simmer, stir for 2-3 minutes to dissolve the sugar fully, then add 2 1/2 cups figs.
Stir so that the figs are coated in the red wine. Let simmer for 12-15 minutes, stirring only occasionally, as the red wine reduces by half. When you can swipe a spatula across the pan and see the bottom for a few seconds, the figs are finished.
Transfer the figs to a bowl and let them chill in the fridge for 1 hour.
When the figs are fully chilled, begin the scones.
Position a rack to the center of the oven and preheat to 375°F.
Either grate or chop 226 grams of butter into 1 cm square cubes. Place them in the freezer while you prep the other ingredients.
Whisk together 420 grams of flour, 50 grams of granulated sugar, 1 tablespoon of baking powder and 1 scant tablespoon of salt in a large bowl. Remove the butter from the freezer and add it in. Tossing to coat the butter fully in flour, mashing up the pieces so they all lay flat.
Add half the buttermilk and mix it in with a fork. Add the second half and mix again. The dough should be crumbly, but beginning to get sticky.
Transfer the crumbly dough onto a clean (and preferably cold) work surface. Using your hands, gently press the crumbs together. Fold the dough over, press and shape again, then rotate 90 degrees and repeat the process. The dough will stay crumbly, but it will start to come together. Pat it down until it is 2 inches thick.
Use a bench scraper to cut the dough into thirds. Take 1/4 cup of the figs and layer it on top of one piece of dough, press another piece of dough on top. Layer more figs onto that piece of dough, then layer the last piece on top. Press it down to laminate the figs inside the dough.
Cut the dough into halves, add another layer of figs and laminate again. Press the dough down, cut it in half, and stack it on top of itself and press down again. You'll start to see layers of bright purple figs.
Pat the dough down into a large circle, about 2 inches thick and 10-12 inches wide. Slice the circle into 8 pieces.
Arrange the scones out on a parchment-lined baking sheet. Brush the tops with buttermilk and sprinkle with 2 tablespoons of turbinado sugar.
Bake for 30-35 minutes, or until deeply golden on top. Enjoy warm!
