Preheat oven to 200°C/390°F (180°C fan). Line tray with baking/parchment paper.
Combine the flour, cream and lemonade in a bowl and mix until flour is mostly combined. Do NOT over mix, it will make the scones dense. The dough should be soft and fairly sticky.
Turn out onto a floured surface, and knead very gently just 3 - 5 times to bring dough together, then gently pat into a disc shape 2.5cm/1" thick.
Cut into rounds or squares
Use a knife to scoop up (avoid touching sides) and place on tray, slightly touching each other (they help each other rise).
Brush the tops lightly with milk
Bake for 15 minutes until golden on top. Place on rack to cool. Place tea towel over them to stop the tops from getting crusty.
