Out and out this is the tastiest cauliflower cheese I’ve had the pleasure of eating. Place the cauliflower trimmings, including the stem and leaves, in a pan and pour over the milk. Place another large pan on a medium heat. Stir to combine, turn up the heat a little and fry for 6–8 minutes, until the cauliflower has softened. Add all but a handful of the cheese to the sauce and stir it in well to melt.
