Preheat the oven to 220°C/425°F (200°C fan), and line a baking tray with baking paper.
Add the flour to the Thermomix and mix for 5 sec/speed 5.
Add the cream and lemonade and knead for 1 minute/dough function. It should now have come together. Scrape down the sides of the mixing bowl and stir in any stray bits of mixture stuck to the side of the bowl.
Tip the mixture onto a lightly floured surface and gently knead into a ball. Don't overwork the dough, or the scones will be dense. Pat the dough down with your hands to a 2.5-3cm thickness.
Cut out rounds with a 6cm pastry cutter and place them onto the baking tray. Dip the cutter in flour first so it doesn't stick to the dough. Brush the tops with a little milk - this gives them a lovely shine, but you can skip this step.
Transfer the scones to the baking tray carefully and bake for 12-15 minutesuntil golden.
Cool on a wire rack and enjoy while they are still warm with cream, jam or lemon curd.
Notes
Storage: Scones can be stored in an airtight container for three days. Reheat them for a few seconds in the microwave before serving. The scones can also be stored in the freezer for up to 3 months.
