Add enough cream so the mixture is smooth but slightly thick. Season with salt and pepper.
Fill each mold with the fish mixture.
Place the molds in a baking dish and fill with water, enough to come up 1-inch of the mold. Place in the oven and cook for about 12 to 15 minutes or until firm. Remove from the oven and cool completely.
Refrigerate until chilled. Slice the lobster tails, 1//4-inch thick. In a mixing bowl, combine the lobster, peas, and carrots. Toss with a drizzle of truffle oil. Season with salt and pepper. Add the chervil and toss well.
