Preheat the oven to 180C.
Combine the SR flour, wholemeal Flour and sugar. Then use your hands to rub the butter into the flour to create a crumb. Then add in the buttermilk. Bring it together in a stiff dough. Tip onto a floured surface and gently knead until smooth. Pat out to 2cm thick. Use a scone cutter to cut scones.
Bake in the oven for 20mins.
Serve with cream and your favourite jam!
