Directions

this recipe

1. Cook the Lobsters: Boil the lobsters in salted water for about 8–10 minutes until bright red. Remove, let cool, and split in half lengthwise. Remove the meat from the tails and claws; chop and set aside. Reserve the shells for serving.
2. Prepare the Sauce: In a saucepan, melt the butter over medium heat. Add the shallot and garlic and sauté until softened. Stir in the flour and cook for 1–2 minutes. Gradually whisk in the wine, fish stock, and cream. Simmer until thickened, about 5 minutes.
3. Add Flavor: Stir in the mustard, tarragon, lemon juice, and cognac. Season with salt and white pepper. Add the chopped lobster meat and half of the Gruyère. Stir to coat and heat through.
4. Stuff and Top: Spoon the mixture into the reserved lobster shells. Sprinkle with the remaining Gruyère and Parmesan.
5. Broil: Preheat broiler. Place stuffed lobster shells on a baking sheet and broil for 3–4 minutes, or until cheese is bubbling and golden brown.
6. Serve: Garnish with extra herbs and serve hot with lemon wedges or over rice.
