Warm milk in the microwave for ~ 1 min. The milk shouldn't be scalding hot, just warm. Add the earl grey tea bag to the milk.
Mix together in a large bowl flour, sugar, salt, and baking powder.
Cut butter into flour mixture until it resembles coarse crumbs.
Add egg, vanilla paste, and vanilla extract to the warm tea infused milk.
Remove the tea bag from the milk. Add the milk to the flour mixture.
Gently mix the scones until just combined. Do not overmix.
Roll out the scone dough until the thickness is 1/2". Cut the scones in small triangles (2-2.2" inches long).
Bake the scones at 425 degrees F for 8-11 minutes until just browning on the edges.
Let the scones cool.
