I take a pair of scissors and cut the top shell down the middle. I put them on direct heat top side down for about 3 minutes, flip them, lightly pour butter and garlic inside shell, and cook for "maybe" for another 3 minutes. The shell kinda opens up a little bit. The meat pulls away from the shell. Note I only cooked little tails , not the big daddy's. I don't know if the butter does anything but flare up a fire. I would rather wait and put butter and garlic in a cup to dip the meat in when I plate but my wife is with me to bark orders.
