Cut the 75 grams Unsalted Butter into small cubes about 1 cm, ⅓” in size, to not only work into the dough better, but for quicker softening. **Please note, no requirement to use fridge-cold butter for scones. We just want to soften a little to make easier to work with.
Add the 450 grams Plain Flour, and 7½ tsp Baking Powder to a mixing bowl. This is 2½ tbsp & correct amount. (For UK self-raising flour, only add 2 level tsp of baking powder).
Briefly mix to coat, then use a pastry cutter (pastry blender), 2 butter knives or your fingers to 'cut in' or 'rub in' the butter. (For a detailed look at this process, see the step-by-step instructions). Aim for roughly large breadcrumb consistency. **DO NOT USE A FOOD PROCESSOR.
Now add in the 50 grams Caster Sugar & then make a well in the middle. Place to the side.
Crack the 2 Eggs into a jug, whisk really well, and top up with milk, to the 300ml (10 fl oz) or 1 1/2 cups level. Whisk once more & reserve 2 tbsp for later.
Add in half of the milk/egg mixture to the dry ingredients and start to work in. Very gradually add small amounts of the liquid until the dough starts to come together. You might need a little more or not use all. Use your hands to briefly knead together into a ball then a disc, that is just a little bit sticky.
Flour baking/parchment paper or a work area, & place the disc of dough down in the centre. Use your hands to pat out the dough to a circle or oval shape, with a thickness of at least 1” (2.5cm). Use your heart cutter to try and get 5 scones from this round. **The more you get from the first round, the more perfect shape they will be. DO NOT USE A ROLLING PIN.
