1
Preheat the oven to 220°C.
2
Combine the self-raising flour, salt, and baking powder in a large bowl, and mix them together.
3
Put the butter into the mixture, then use your fingers to combine it until the mixture has the texture of fine crumbs. Mix in the caster sugar.
4
Pour the milk into a jug and warm it in the microwave for approximately 30 seconds until it is warm, but not hot. Add the vanilla extract and lemon juice, and then set it aside momentarily.
5
Place a baking tray inside the oven to preheat it. Create a hollow in the dry mixture and proceed to pour the milk mixture into it. Use a cutlery knife to promptly blend everything together - initially, it might appear excessively moist.
6
Sprinkle some flour onto the countertop and transfer the dough onto it. Sprinkle a bit more flour onto the dough and your hands, then fold the dough over itself 2-3 times until it becomes slightly smoother. Shape the dough into a round shape that is about 4cm thick.
7
Using a 5cm cutter, dip it into some flour and press it into the dough. Repeat this process until you have four scones. If necessary, reshape the remaining dough to cut out another four scones.
8
Coat the tops with the beaten egg before placing onto the heated baking tray. Bake for 10 minutes until they are puffed and have a golden color. Enjoy them either warm or cold on the same day of baking, generously spread with jam and clotted cream.
