Preheat oven to 180 degrees Celsius. Line a cookie sheet with baking paper and set aside
Add the flour,salt and cold butter to a food processor. Pulse until it resembles fine breadcrumbs
Add the buttermilk and pulse again until the dough comes together. Do not overmix
Add the cheddar cheese and chives and pulse again, just a couple of times
Remove the dough from the food processor and place on a flat surface dusted with flour
Press the dough, using your hands, into a rectangle. You can use a rolling pin too if you wish
Fold the rectangle in half, lengthwise. Fold again in half and then into quarters. You will now have a square
Roll or flatten again into a rectangle and repeat the folds
Roll out again and cut into round circles, You can cut them however, large you prefer. I used a small round cutter, about 7cm in diameter so I got mini scones
Place them on the lined baking sheet and brush them with some melted butter. Bake at 180 degrees Celsius for 15 minutes or until slightly golden brown
Cool on wire rack
