Preheat oven to 400* F and line a baking tray with parchment.
Into a mixing bowl, add flour, sugar, baking powder, baking soda and salt. Mix to combine.
2 Cups All Purpose Flour, ½ Cup Granulated Sugar, 2 teaspoon Baking Powder, ¼ teaspoon Baking Soda, ¼ teaspoon Kosher Salt
Add the cubed non-dairy butter and work the butter into the dry ingredients with a pastry cutter, two forks or your hands. Work the butter in until is just smaller than small peas.
1 Stick Non Dairy Butter, COLD, cut into ¼" cubes
Remove the tea from the refrigerator and add the vanilla and vinegar to it. Stir.
1 teaspoon Vanilla, 1 ½ teaspoon Lemon Juice or White Vinegar
Add the tea mixture into the butter and flour mixture and toss everything together with a fork until the mixture is moist.
Pour the mixture onto a work surface and fold it onto itself a few times until the dough becomes cohesive. This will that about 3 folds. See note.
Press the dough into a circle that is about 6-7 inches in diameter and 1 inch tall.
Cut the dough round into 6 triangles.
Transfer the triangles to a parchment lined baking sheet and bake in 400* F oven for 16-18 minutes or until the bottoms of the scones are browned all the way across.
Remove from the oven and allow to cool for 20 minutes before glazing.
