Preheat a deep fat fryer to 180 C, 350 F. Place the flour on a tray, combine the breadcrumbs and cheese in a bowl. Beat the eggs together in another bowl. Lightly dust the cauliflower florets in flour, dip in the egg followed by the breadcrumb mixture, repeating the process until all florets have been coated. Deep fry in batches for 2-3 minutes until golden brown. Drain on kitchen paper and keep warm. To make the dip, mix together the mayonnaise and cream until well blended, stir in the mustard. Leave to stand for 10-15 minutes to allow the flavours to develop. Serve the crispy cauliflower with the mustard dip.
