Chaffing is a technique Paul Hollywood uses to bring a lighter texture to his scone recipe.
-Use your hands to fold the dough in half, then turn the dough 90 degrees and repeat. By folding and turning the mixture in this way (called ‘chaffing’), you incorporate the last of the flour and add air. Do this a few times until you’ve formed a smooth dough. If the mixture becomes too sticky use some extra flour to coat the mixture or your hands to make it more manageable. Be careful not to overwork your dough.
