Heat the oven to 220C/fan 200C/gas 7. Sprinkle a little flour onto a baking sheet. Tip the measured flour into a large mixing bowl and stir in the salt. Add the butter and rub together with your fingertips until the mixture resembles fine breadcrumb (alternatively do this in a food processor by pulsing in short bursts). Stir through the sugar and cherries. Make a well in the centre of the dried ingredients and pour in the milk then mix swiftly to combine. Tip the roughly mixed dough out on to a lightly floured worksurface and bring together with your hands, trying not to overwork the dough.
