Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a large bowl, whisk together the flour, baking powder, salt, sugar, and lavender. Add the butter and use a pastry cutter to work it into the flour mixture until it looks like coarse crumbs.
2 cups (240 g) all-purpose flour, 1 tbsp (12 g) baking powder, ¼ tsp (1.5 g) table salt, ¼ cup (50 g) granulated sugar, 1 tbsp (~ 1 g) fresh culinary lavender, 6 tbsps (85 g) cold unsalted butter
In a separate bowl, whisk together the honey, cream, and egg. Pour that into the dry ingredients and fold everything together with a spatula until just combined. The dough will be slightly sticky.
⅓ cup (113 g) honey, ½ cup (120 ml) cold heavy cream, 1 large egg
Turn the dough out onto a floured surface and gently pat it into a circle about 1 inch (2.5 cm) thick. Cut into 8 wedges and place them on the prepared baking sheet. Brush the tops lightly with cream.
Bake for 18 to 22 minutes, or until the edges are golden. Let the scones cool on a wire rack for 10 minutes while you make the glaze.
In a small bowl, stir together the confectioners' sugar, honey, lavender, and milk until smooth. Strain the juice from a few crushed blueberries or blackberries and stir in 1 to 2 teaspoons of the juice for a soft purple color. If the glaze is too thick, add more milk a little at a time until it’s pourable. Drizzle over the cooled scones.
1 cup (120 g) confectioners' sugar, 1 tbsp (21 g) honey, 1 tsp (~0.3 g) fresh culinary lavender, 1-2 tbsps (15-30 ml) milk, 1-2 tsps (5-10 ml) strained juice from crushed blueberries or blackberries
Garnish with extra lavender flowers if you like.
