Meanwhile, whizz the cheese (only 1 tbsp of the Parmesan), milk and cornflour together in a food processor. Stir through the mustard, then transfer to a shallow baking dish or an ovenproof pan (ours was 15cm across and 3cm deep) and scatter with the remaining Parmesan. Reduce oven to 160C/140C fan/gas 3 after the sprouts have had their initial cooking time. Place the cheese dish on the top shelf of the oven and bake for 15 mins, with the sprouts on the tray below.
