Preheat oven to 425 degrees.
Mix flour, sugar and baking powder together in a bowl. Cut butter into chunks and mix into dry ingredients until it is crumbly. Mix in the zest of one lemon.
Add buttermilk, dried fruit (optional), and mix together, kneading gently until you form a ball.
To shape the scones, grease and flour a 9" cake pan and press the dough into it (though this is optional, you can make the scones any shape you want).
Turn the dough out of the pan and cut it into triangular wedges. Place the wedges on a baking tray lined with parchment and bake for 15 minutes.
Allow scones to cool completely on a baking rack before glazing them with icing:
Add lemon juice to powdered sugar slowly, as you will likely need less than you think you do! Mix until you have a consistency that is like honey and drizzle over your scones.
