How to Make It
Preheat oven to 450°F. Stir together flour, sugar, baking powder, and salt in a medium bowl. Using a pastry cutter, cut butter into flour mixture until mixture is crumbly and resembles small peas. Freeze mixture 5 minutes.
Stir in thyme, orange blossom water, and 3/4 cup plus 2 tablespoons of the cream just until dry ingredients are moistened. Place dough on a sheet of wax paper. Gently press dough into a 7-inch round. (Mixture will be crumbly.) Cut round into 8 wedges. Place wedges 2 inches apart on a baking sheet lined with parchment paper. Brush tops of wedges with remaining 2 tablespoons cream just until moistened. (You may not need all of the cream.)
Bake in preheated oven until golden brown, 13 to 15 minutes. Brush warm scones with Orange Blossom Glaze.
