In a medium bowl, thoroughly combine the butter, garlic and listed seasonings to create the Smoked Garlic Butter.
Prepare the grill for direct grilling over a hot fire. A natural lump charcoal fire is preferred.
From the meat side of the lobster tails, use kitchen shears to cut down towards the tails on either side of the soft belly. Peel back the underside of the shell, and gently remove lobster meat starting from the tail end. Lift the meat so it is resting on top of the shell.
Lay the tails meat side down and insert skewers on either side of the tail. Baste flesh with Garlic Butter and set aside.
Once your fire is at 400°F, lay the tails meat side down directy on the hot grill grate, for 1 1/2 - 2 minutes. Turn, then baste with more Smoked Garlic Butter and cook for another 5-6 minutes. Remove once the meat turns from transparent to opaque, an internal temperature of about 135°F. To serve, drizzle with extra butter and parsley.
