Preheat your oven to 220°C (425°F) and line a tray with baking paper. If you're using a fan or convection oven, set it to 200℃ (400℉) instead.
Mix the flour, salt and baking powder together in a large bowl.
Rub the butter in to make a breadcrumb-like mixture then stir in the caster sugar.
Make a well in the middle of the dry mixture then pour the milk into it. Mix well then press everything together into a rough ball of dough. Do not overwork it or you'll end up with tough scones.
Gently press the chopped apricots into the dough.
Roll the dough out to around ¾-inch thick and cut out your scones using a 3-inch round cutter. You should end up with roughly 8 scones.
Place the scones close together on your lined tray then brush the tops with the beaten egg.
Bake for 12-15 minutes, until golden brown on top and cooked through. If the tops have browned before the centre is cooked, cover the tray with tin foil and bake for a few minutes longer.
Once cooked, transfer them to a wire rack and leave to cool completely.
Mix the icing sugar and lemon juice together to make the glaze then drizzle it over the scones. Serve with butter or with whipped cream and apricot jam.
