Preheat the oven to 375 F. Lightly grease a baking sheet or line with parchment paper. Measure out the milk and add the vinegar to it. Set aside to curdle.
Mix together the flour, baking powder, salt and sugar in a large mixing bowl. Add the shortening in small clumps, then use your fingers to cut it into the flour until it appears like small pebbles. (You an also use a food processor for this, but I prefer to use my hands.) Mix in the lavender.
Create a well in the center and add the soy milk, oil and vanilla. Mix with a wooden spoon just a bit, then add in the berries. Mix again until everything is moistened, but don’t overmix. A couple of dry looking spots are just fine.
Use a 1/4 cup measuring up to scoop the scones out on to the baking sheet. Spray it wth cooking spray first so that the batter comes out easier.
Sprinkle tops with a bit more sugar, then bake for 18 to 22 minutes, until tops are firm to the touch and lightly browned. Serve warm!
