This will instantly kill the lobsters. You are then ready to proceed with your lobster bake. Place a large baking sheet on the grill. Add the water. Arrange lobsters, clams, mussels and shrimp on top of the seaweed.
Sprinkle thinly slices lemon slices over the fish.
Cover with the remaining seaweed. Turn the grill on low and close the cover. The Lobster bake should be done in about 15 - 20 minutes or when the clams and mussels have opened.
