Use a mandolin carefully to slice all the vegetables thinly and construct layers of different coloured vegetables in an oven proof dish gently greased with butter. Sprinkle some of the cheese in amongst different layers and repeat until the oven dish is full. Warm your milk with thyme, nutmeg and seasoning and pour gently over the root vegetables. Top with additional cheese and bake in the oven at 180 ̊C for 1 hour. For best results serve immediately with game to complement the sweetness and earthy profiles.
