I've had people say this is the best lobster dish they ever ate. I played around with this recipe because this is similar to the way my Mom used to make it, but she didn't go by recipes. Living near New Bedford and having the luxury of all the fresh seafood markets available, I usually buy my lobsters live and cook them at home and pick them myself. The biggest one I ever cooked was 10 1/2 pounds. This recipe calls for the tomalley, the green stuff in the head, not absolutely neccesary but it adds a nice flavor to the topping. If you have access to a fish market that has fresh lobsters and ask the fish monger to save you some of the tomalley it will make a difference. I didn't include a measurement for the tomalley because it depends on what you get from the lobster. If you have the fish market cook the lobster, tell them not to over cook it because the meat will cook again. My last 8 1/2 pounder I only boiled for 30 minutes, no more. You will need a batch of Hailey's Favorite Cheese Sauce, recipe #364959 for this. I usually do individual casserole dishes for everyone but you could easily do this in a bigger dish, your choice. The cook or prep time does not include cooking the lobster or picking the lobster or the cheese sauce time. I've also used this recipe with scallops.
