Directions
Begin by cooking the lobster. Bring a large pot of salted water to a boil and cook the lobster until just done. Remove and allow it to cool slightly before splitting it lengthwise. Carefully remove the meat from the claws and tail, chopping it into bite-sized pieces. Reserve the shells for serving.
In a skillet over medium heat, melt the butter and add the finely chopped shallots. Cook until softened, then add the garlic and cook briefly until fragrant. Pour in the white wine and allow it to reduce by about half.
Lower the heat and stir in the cream and Dijon mustard. Simmer gently until slightly thickened. Remove from heat and whisk in the egg yolk, stirring constantly to prevent curdling. Fold in the lobster meat and season with salt and black pepper.
Spoon the mixture back into the reserved lobster shells. Sprinkle generously with Gruyère cheese and a light dusting of paprika. Place under a hot grill until the top is golden and bubbling.
Remove from the oven and garnish with fresh parsley before serving immediately.
