Instructions

  1. 1

    If using live lobsters, dispatch humanely and split in half lengthwise. Remove the stomach sac and intestinal tract. Brush with butter and grill (broil) cut-side up for 8–10 minutes until just cooked. Remove the meat from the shells and dice into large chunks. Reserve the shells.

  2. 2

    Make the sauce: melt the butter in a saucepan over medium heat. Cook the shallots for 3 minutes until soft. Add the white wine and stock and simmer until reduced by half, about 4 minutes.

  3. 3

    Add the cream and simmer for 5–6 minutes until the sauce coats the back of a spoon.

  4. 4

    Remove from heat. Stir in the Dijon, tarragon, chervil, and lemon juice. Season with salt, white pepper, and a pinch of cayenne.

  5. 5

    Fold the lobster meat gently into the sauce. Spoon the mixture back into the reserved lobster shells.

  6. 6

    Scatter the Gruyère generously over the top. Grill (broil) under a high heat for 3–4 minutes until the cheese is golden and bubbling. Serve immediately with lemon wedges and crusty bread.
