Preheat the oven to 400 degrees and grease a baking sheet.
In a large bowl, whisk together the flour, sugar, baking powder, baking soda and salt until blended.
Using a pastry blender or two butter knives, cut the butter into the flour mixture until the butter is about the size of small peas.
Make a well in the center of the butter-flour mixture and add your faux buttermilk all at once. You may stir the mixture with a fork until the dough pulls away from the side of a bowl, if you wish.
Once the liquid has been absorbed, turn and press the dough gently down into the bowl a few times. This gathers up all of the loose butter-flour mixture.
Divide the dough into four parts. Shape each part into a ball and place on a lightly floured board. Lightly pat each ball into a circle.
Cut each circle into four parts and place the wedges on the prepared baking sheet.
Bake until golden, about 15 minutes. Place on a rack to cool.
Serve warm topped with clotted cream or jam.
