Instructions:

Part 1: Build the Seafood Essence (The Soul of the Dish)

1. Cook the Lobster: If using live lobsters, steam or boil them for 10-12 minutes until bright red. Cool, then pick all the meat from shells and claws. Chop into bite-sized pieces. RESERVE ALL SHELLS.

2. Make the Seafood Broth: In a large pot, melt 2 tbsp butter over medium heat. Add the reserved lobster shells and shrimp shells. Sauté for 5 minutes until fragrant and pink. Add onion, carrot, celery, garlic, bay leaf, and peppercorns. Cook for 5 more minutes.

3. Deglaze and Simmer: Stir in tomato paste and cook for 1 minute. Pour in brandy (if using) to deglaze. Add water or stock. Bring to a boil, then reduce to a simmer for 25 minutes. Strain through a fine-mesh sieve, pressing on solids. You should have about 3 cups of deeply flavorful broth. Set aside.

4. Cook the Shrimp: Pat shrimp dry. In the same pot, heat remaining 2 tbsp butter over medium-high. Sear shrimp for 1-2 minutes per side, just until opaque. Remove immediately and set aside with the lobster meat.

Part 2: The Luxurious Cheese Sauce

5. Cook the Pasta: Boil pasta in salted water until al dente (1-2 minutes less than package directions). Drain and toss with a bit of oil to prevent sticking.

6. Make a Roux: In a large, heavy-bottomed pot or Dutch oven, melt 6 tbsp butter over medium heat. Whisk in flour and cook, stirring constantly, for 3-4 minutes until it smells nutty and is light golden (a blond roux).

7. Create the Béchamel: Gradually whisk in the warmed milk and cream until smooth. Then, whisk in the 3 cups of reserved seafood broth. Bring to a gentle simmer, stirring often, until thickened enough to coat the back of a spoon, about 8-10 minutes.

8. Build the Cheese Sauce: Reduce heat to low. Whisk in the Dijon, smoked paprika, and cayenne. Gradually add the grated Gruyère, white cheddar, and ¾ cup of the Parmigiano-Reggiano, stirring until melted and smooth. Season carefully with salt (cheese is salty) and white pepper. Sauce should be luxurious and velvety.

Part 3: Assemble & Bake

9. Combine: Gently fold the cooked pasta, lobster meat, shrimp, and fresh tarragon into the cheese sauce. Pour everything into a large, buttered baking dish (9×13 inch or similar).

10. Make the Topping: Combine panko, melted butter, parsley, and the remaining ¼ cup of Parmigiano. Sprinkle evenly over the mac and cheese.

11. Bake: Bake at 375°F (190°C) for 25-30 minutes, until the topping is golden brown and the sauce is bubbling around the edges. If the top browns too quickly, tent with foil
