👨🍳 Instructions
-
1
Bring a very large pot of salted water to a rolling boil. Submerge the lobsters head-first and cook for 8-10 minutes until they turn bright red. Immediately plunge them into an ice bath to stop the cooking process.
-
2
Once cooled, place the lobsters on a cutting board. Using a sharp chef's knife, split them in half lengthwise from head to tail. Remove the intestinal vein, the grit sac near the head, and the spongy gills.
-
3
Carefully extract the meat from the tails and claws. Crack the claws gently to keep the meat as whole as possible. Cut all the lobster meat into bite-sized 1-inch chunks.
-
4
Wash the empty lobster shells thoroughly and pat them dry. Place them on a parchment-lined baking sheet and set aside; these will serve as your 'bowls'.
-
5
In a medium saucepan over medium heat, melt the butter. Add the minced shallots and sauté for 2-3 minutes until translucent and soft, but not browned.
-
6
Whisk in the gluten-free flour to create a roux. Cook for 1-2 minutes while stirring constantly to remove the 'raw' flour taste.
-
7
Slowly pour in the white wine and cognac while whisking vigorously to avoid lumps. Let the liquid simmer for 2 minutes until reduced by half.
-
8
Gradually whisk in the heavy cream. Lower the heat and simmer gently for 5 minutes until the sauce thickens enough to coat the back of a spoon.
-
9
Remove the pan from the heat. Stir in the Dijon mustard, mustard powder, fresh tarragon, and lemon juice. Season with salt and white pepper to taste.
-
10
Temper the egg yolk by adding a tablespoon of the hot sauce to it, whisking quickly, then pour the yolk mixture back into the main sauce. This adds a beautiful silken gloss.
-
11
Fold the prepared lobster meat into the sauce, ensuring every piece is generously coated. Divide the mixture evenly among the four lobster shell halves.
-
12
In a small bowl, mix the Gruyère, Parmesan, and paprika. Sprinkle this mixture liberally over the top of the lobster meat.
-
13
Preheat your broiler (grill) to high. Place the baking sheet under the broiler for 3-5 minutes, watching closely, until the cheese is bubbling and turns a deep golden brown.
-
14
Garnish with a final sprinkle of fresh tarragon or parsley and serve immediately while piping hot.
💡 Chef's Tips
Always use freshly grated Gruyère; pre-shredded cheeses are often coated in potato starch which can affect the melting texture. If your gluten-free flour blend doesn't contain xanthan gum, add a tiny pinch (1/8 tsp) to ensure the sauce doesn't separate. Don't overcook the lobster during the initial boil; it will cook further under the broiler, and overcooked lobster becomes rubbery. To prevent the shells from wobbling on the baking sheet, create small 'nests' out of crumpled aluminum foil to hold them steady. For an even deeper flavor, you can sauté the lobster shells in butter before making the sauce to create a quick lobster butter base.
🍽️ Serving Suggestions
Serve with a side of buttery steamed asparagus or haricots verts to cut through the richness of the sauce. A crisp, chilled glass of Chablis or a dry Champagne is the traditional and perfect beverage pairing. Accompany with a simple wild rice pilaf or crusty gluten-free baguette slices to soak up the extra sauce. A light arugula salad with a lemon vinaigrette provides a refreshing acidic contrast to the decadent cream.
