Cube the 75 grams Unsalted Butter into small pieces, roughly 1 cm, ⅓” in size for quicker softening. No need for fridge-cold butter for scones.
Once the butter is soft enough to leave an indent with your thumb, add the 450 grams Gluten-free Plain Flour , the 1⅛ tsp Xanthan Gum and 7½ tsp Baking Powder to a mixing bowl. *** (For Plain/A.P. flour add the 2½ tbsp baking powder. For UK self-raising flour, only add 2 level tsp of baking powder).
Mix briefly before adding in the butter cubes, and little mixing. Use a pastry cutter (pastry blender), 2 butter knives or your finger tips to ‘cut in’ or ‘rub in’ the butter. You are aiming for a rough large breadcrumb consistency. (For more on this see the step-by-step directions & images before this recipe card, or watch the video). DO NOT USE A FOOD PROCESSOR.
Mix in the 50 grams Caster Sugar & make a well in the centre before placing to the side.
Break the 2 Eggs into a jug & give a really good whisk, before topping up with milk, to the 300ml (10 fl oz) or 1 1/2 cups level. Whisk again and reserve 2 tbsp for later.
Add half of the milk/egg mixture to the dry ingredients and start to work in. Gradually add small amounts of the liquid until the dough starts to come together. You might not need all of the liquid or a little more. Get your hands in when starting to form and knead very briefly to form into a ball and then a disc. The dough should be just a little bit sticky.
Lightly flour some baking/parchment paper and place down the disc of dough. Use your hands to pat out the dough. DO NOT USE A ROLLING PIN. Start from the centre and pat out to a thickness of at least 1” (2.5cm).
