In a small saucepan, preferably one that will work on your grill, heat the butter, salt and garlic. Heat until the butter fully melts and then set to the side.
Prepare your grill for direct cooking over medium/ high heat. Make sure to brush the grates clean. For this one, I used the charcoal grill. The flavor really comes across in the lobster. This works great over a gas grill too.
To prepare the lobster cut the top of the shell with a pair of sheers. Cut right through the center of the shell down the middle of the lobster tail.
Flip over and do the same on the bottom of the tail.
Then using a sharp knife cut the lobster in half. Season the lobster with a little salt and then brush it with the garlic butter.
Place the lobster directly over the heat with the meat side down. Grill for 2-3 minutes until the meat turns opaque.
Flip the lobster and brush with the garlic butter. Continue to grill until the lobster meats is slightly firm, roughly 3 minutes.
Remove the lobster and serve.
