Preheat the oven to 425 degrees F. 2Place the parchment lined baking sheet in the oven to preheat as well.
In a large mixing bowl combine flour, baking powder, sugar and a pinch of salt. Stir to combine. Then add 6 tbsp of cold, cubed butter. Use your hands to pinch the butter into the flour until well incorporated with a sandy texture. Set aside.
In a separate bowl whisk together eggs, milk, vanilla extract and lemon juice until well combined. Then stir in chopped dates.
Use your hands to form a well in the center of the flour mixture then pour the milk mixture in. Cut the weight and dry ingredients until a dough is formed. Then tip the dough onto a floured surface and knead a few times (being careful not to overwork) to bring the dough together. Then use a rolling pin to carefully roll the dough out to 1 - 1.5 inch thickness. And use a round cookie cutter or biscuit cutter to cut out the scones. Arrange the scones on the preheated cookie sheet.
In a small bowl whisk together 1 egg yolk with a splash of milk or cream. Then brush over the tops of the scones and sprinkle with a little turbinado sugar. Bake at 425 degrees F for 12-15 minutes until golden brown and cooked through. Allow the scones to cool for at least 15-30 minutes before serving. Enjoy!
