Heat the oven to 220ºc/200ºc fan/430F and place a lined baking tray in the oven to preheat.
In a large bowl, rub the butter into the flour, salt, baking powder and sugar mixture until breadcrumbs are formed.
Alternatively, tip the flour, salt, baking powder, sugar and butter into a food processor and pulse until it resembles bread crumbs
Add the lemon juice to the dry mixture with the vanilla
Slowly add the warm milk. Mix in while you add in the liquid as you may not need all of it - you can do this with a spatula, or still in the food processor
Fold in the chopped up chocolate and dried cranberries
Dust the work surface with some flour and tip the dough onto it - fold the dough over a few times so it is smooth but do not over work it
Flatten the dough out until it is about 5cm thick
Dip a 5cm round cutter into the spare flour and cut out the scones
Flatten out the dough again and cut the rest out until the dough is all used up - trying not to over work the dough
Carefully place the scones onto the baking trays and brush the tops with the beaten egg so its glazed
Bake in the oven for 10 minutes then leave to cool slightly
Serve with clotted cream and jam for the stereotypical delicious scone
Notes
You could easily make this mix and use a smaller cutter so that the scones are more delicate which I often do – I then usually get 12 out of the mix.
I often find these are delicious when still warm as it makes them lighter and fluffier
Be careful not to mix the white chocolate in too early, or the heat of the milk that was poured in will melt it - which may not be a bad thing, but it might change how light the texture is, and I love the chocolatey chunks running through!
You can use plain flour, and use 2tsps baking powder instead
You can swap the milk and lemon juice for buttermilk - skip the heating stage and just add it to the dough
