while the lobster is alive with a big knife cut him in half from the top of his head to the tip of the tail. get a spoon and scoop the guts out and save em.
in a hot saute pan saute some minced shallots, garlic, then add your halfed lobster to the pan meat side down. cook for a couple minutes then add a couple ounces of sherry wine some lemon juice and some lobster or seafood stock anbout 6 oz. turn the lobster halfs over so they are shell side down and cover and let it cook for a bout 4-6 min untill the lobster is fully cooked.
remove the lobster from the pan in the same pan saucte some diced prtabella mushrooms, chopped parsley and a pinch and a half of fresh chopped tarrgon and scallions then and throw the guts (the proper term is tamale) back in the pan and saute, once fully cooked add a few ounces of heavy cream and season with white pepper and salt throw in some already cooked and cooled pasta and toss untill it is coated with sauce and hot.
to plate put pasta in a bowl remove the tail and claw from the lobster body. crack the claw open so the meat is exposed and lay it on the pasta.
