Preheat your oven to 180°C. Line a baking tray with baking parchment.

Add a knob of butter to a small frying pan, and fry the chopped sage for a couple of minutes (keep a few leaves back to decorate).

Sift your flour into a large mixing bowl. Add the cubed butter and gently rub it into the flour using your fingertips until you have a breadcrumb-like consistency.

Add the salt, grated Double Gloucester, buttery chopped sage, black pepper and baking powder and combine evenly. Slowly add the egg and buttermilk to the mixture. Work the mix with your hands to achieve a dough that is slightly on the wet side, but not sticky,

Lightly flour your work surface and roll the dough out until it is about 4cm thick using a rolling pin.

Use a pastry cutter to cut out your scones and place them on a baking tray. You can re-form the scraps and roll them out again until you have used as much of the dough as possible.

Place on the baking tray, garnish the tops with any leftover sage leaves, and glaze with a little buttermilk using a pastry brush, fixing the leaves firmly into place.

Bake for 25-30 minutes until risen and golden. Transfer to a wire rack to cool, and eat on the day of making.
