No, this recipe for grilled lobster tail does not require that you steam or boil your lobster first.  This is often done to help set the meat and make it easier to separate from the shell after cooking, but it is not necessary. In this smoked lobster tail recipe, the tails are split open and the meat is mostly separated from the shell before you ever start grilling. This takes away the need to steam first.  However, if you want to steam your lobster tails first, keep in mind that your grilling time will be drastically reduced. Make sure you don’t ruin your grilled lobster by overcooking it.
