1. Boil: Bring 3 quarts of water to a rolling boil in a 6-quart saucepot. Pierce the haggis casing once with a fork, carefully lower it into the boiling water, and cook for 45 to 60 minutes until firm and hot.

2. Simmer: Place the cubed potatoes in a 3-quart pot and add enough water to cover them completely. Bring to a boil over high heat, then lower the heat to low, cover, and simmer for 20 minutes until completely tender.

3. Cook: Place the cubed turnips and 1/2 teaspoon of salt in a 2-quart pot, covering them with water. Bring to a boil, reduce the heat to low, cover the pot, and cook for 25 to 30 minutes until the turnip pieces are tender.

4. Mash: Drain the tender potatoes well and return them to their pot. Mash thoroughly to break up all chunks, then incorporate 1/2 teaspoon of salt, 2 tablespoons of melted butter, and half of the warm milk until smooth and fluffy.

5. Season: Drain the cooked turnips completely, return them to their saucepan, and stir in the remaining 2 tablespoons of melted butter. Keep both your potato and turnip mashes covered and warm until you are ready to plate.

6. Plate: Transfer the cooked haggis to the center of a large serving platter. Spoon neat mounds of the mashed potatoes around the haggis, leaving even gaps between each scoop.

7. Fill: Spoon the warm mashed turnips directly into the open spaces between the potato mounds to encircle the main dish beautifully.

8. Garnish: Decorate the platter with fresh sprigs of lavender, rosemary, and sage. Serve the meal hot alongside individual shots of Scotch whisky to pour over the portions or sip on the side.
