Preheat oven to 400 degrees and line a baking sheet with parchment paper
In a large mixing bowl, mix dry ingredients and lemon zest (flour, sugar, salt, baking powder)
In a glass measuring cup, mix milk, egg, lemon juice, vanilla and almond extracts
Using a cheese grater, grate the cold butter into dry ingredients and mix
Add milk mixture to bowl and mix until dough is combined (you may need to use your hands to knead it a few times until it comes together
Working quickly before the butter melts, turn dough out onto lightly floured counter and shape into a disk (about 1.5 inches thick)
Cut into 8 even pieces and place on lined baking sheet, space about an inch apart
Brush each scone with the cream (this is the key to perfect bakery style scones)
Bake in preheated oven for 15-18 minutes (check at 15 minutes, they won't brown much on top)
Cool on rack and drizzle with glaze
