In the bowl of a food processor add the flour, baking powder, salt, sugar, and lime zest, pulse 3-4 tiomes to blend.
Add the cubes of butter and pulse until the butter has been cut into the mixture, it should like coarse grains of sand. *you can use a pastry blender to cut in the butter if you don’t want to use a food processor
In a small bowl, mix together the yogurt, cream, and vanilla until combined.
Add the wet ingredients to the flour mixture and mix the combined ingredients with a spoon until the mixture just starts to come together. Do not overmix.
Dump the scone dough onto a lightly floured work surface.
Form the mixture into a ball and use your hands to form the dough into a large circle and flatten till about 1 ¼ inch thick.
Using a drinking glass or cutter cut out the scones in circles, reform any dough left and repeat the process until you've finished using all the dough.
Place the scones on a baking sheet lined with parchment paper. Brush the scones with heavy cream. This will give the scones an amazing golden brown color. (milk can be substituted)*Chilling the cut out scones for 20-30 minutes before baking will give you a flakier scone.
Bake for 15-20 minutes, or until a deep golden brown in color.
Transfer to a wire rack to cool.
