Preheat the oven to 220C/Gas 7/fan oven 200C. Put the flour, baking powder and salt into a food processor. Whizz for a few seconds, then add the butter and whizz until the mixture looks like coarse
breadcrumbs. Tip in 100g/4oz of the wensleydale and briefly pulse to combine, then pour in the buttermilk
and whizz until the mixture has formed a soft, claggy dough. Remove the blade, leaving the dough in the bowl.
Quarter the Bramley apples, then remove the core and peel each wedge. Depending on how quickly you work, drop the peeled apples into a bowl of cold water acidulated with the juice of a lemon, to stop them going brown; drain and dry the apples before proceeding with the recipe.
Butter a 1.2 litre/2 pint ovenproof dish that’s about 23-25cm/9-10in in diameter and 6-7.5cm/21⁄2-3in deep. Thickly slice the quartered apples and pile them into the dish. The apples collapse when they are cooked, so if there isn’t a good mound, add some more. Combine the sugars and ginger, and dredge the apples evenly. (I like to use two sugars: the muscovado has a bullish toffee flavour and the refined is
just sweet, sweet, sweet.)
Using your fingers, plop 5 tangerinesized balls of dough on top of the apples in a circle, plus one in the middle: they’ll look untidy but that’s okay. Carefully sprinkle the remaining cheese over the cobbler scones. Bake for 15 minutes, then reduce the oven temperature to 190C/Gas 5/fan oven 170C and
continue baking for 20 minutes until the apples are tender and the cobbler is beautifully brown. Serve with a generous dollop of mascarpone.
