In a large mixing bowl, whisk to combine the dry ingredients (570 g all-purpose flour, 48 g baking powder, 1 tsp. saltand 150 g sugar) in a large bowl, and mix in the 170 g unsalted butter with a hand mixer or manually until the butter is completely distributed. You shouldn’t see any chunks of butter, and the mixture should have a sandy texture to it.
In a small mixing bowl, whisk to combine the 325 ml milk and 2 egg. [IMPORTANT] Save 4 tbsp or 60 ml of it for the egg wash later, and pour the rest into the mixing bowl with the dry ingredients.Stir to combine with a spatula, until a rough dough forms.
The Shaping
Transfer to a lightly floured countertop and knead about 10 times until the dough comes together into a relatively smooth ball. Take care not to knead too much, or the dough will be tougher and not rise as high.
Roll the dough about an inch thick and use a 2.5″ cutter to cut. When done, re-roll the scraps and cut out more. Repeat until all the dough is used.
The Baking
Place the scones onto a parchment lined baking sheet and brush the tops with the reserved egg wash.
Bake the scones for 15 minutes, until about tripled in height, and golden brown on the tops and bottoms.
The Serving
Spread them with your favorite jam, sour cream, butter or simply eat them plain.
