Method:

1. Preheat oven to 200°C. 
2. Combine the flour, sugar, salt, baking powder and baking soda in a large bowl. 
3. Add butter and mix with your fingertips to a coarse meal. 
4. Add buttermilk and mix just until combined. 
5. Leave it crumbly and not fully combined.
6. Transfer dough to a floured board. 
7. Gently pat the dough and crumbs to combine. 
8. Flatten it to a rectangle. 
9. Lift both ends and fold inwards to the centre with a scraper (like a 3 fold business letter). 
10. Rotate 90°. 
11. Pat down to a rectangle again and repeat folding. 
12. Do this 3 times or until your dough comes together.
13. Finally flatten out with your palm or rolling pin and cut with a sharp cookie cutter with a straight downwards motion. Do not twist the cutter. 
14. Lay the cut pieces on a greased baking paper thats placed on a tray. 
15. Brush the tops with eggwash, and bake for 15 minutes, or until lightly browned. 
16. Serve warm, split in half and top with butter, jam and cream.

*I make my own buttermilk by adding 1 tbsp of White Vinegar to 200ml of Full Cream Milk.
