You will require a ring mould for this dish.
Boil the macaroni. Grease a ring mould with butter. Chop the lobster and reserve 3 or 4 neat pieces and 12 prawns for decoration.
Stir all the rest of the shellfish into the macaroni and mix in
Meanwhile make the white sauce and stir in the rest of the cream and the cooked cucumber. Season highly with salt and white pepper. Keep warm.
Take the ring mould out of the oven and unmould. Pour the sauce into the centre of the ring. Sprinkle the parsley lightly all round the top of the ring but not on to the sauce.
Place the reserved shellfish around the top of the ring on the parsley and serve immediately.
