Preheat oven to 200°C
In a large bowl, add flour, salt, sugar, baking powder and soda. Mix well.
Grate the frozen butter and add to the flour. Grate half, mix it in and then grate the other half. Mix with a spatula.
Make a well in the center and pour buttermilk. Mix until just combined.
Add a generous amount of flour on the work surface and drop the flour mixture on it.
Press and knead the dough gently until it becomes manageable. Dont overwork it or add lots of flour to it, otherwise the biscuits will become hard and flat. Always wet dough gives the best biscuits.
Spread the dough and fold it as shown in the video. Fold it about 4 times.
Pat the dough and spread it into a 1 inch thick rectangle.
Dip the cookie cutter in flour and cut out the biscuits. Remember to not twist the cutter, just press it and cut. Twisting will seal the edges and it won’t rise well.
Place it in a baing tray close to each other with sides touching. Bake for 14 minutes until the top turns golden brown.
Brush the tops with melted butter and serve warm.
