I grew up in a lobstering family never short of 'em for free, and we
always did that (for 2 1/2 pounders, anything bigger was unfit to eat &
anything much smaller was for selling). But times advance. It may
sound tacky to you, but it's hard to beat what a microwave will do for
lobster tails & big crab legs in the shell. Put grill marks on 'em
after that for 15 seconds if you have to have the citified tourist look
to your food at the expense of some taste. No lobsterman would split a
lobster tail & ruin it on a grille, unless it was one of those
warm-water make-believe lobster tails that need to be dried out &
burned a little to seem like seafood, and to add a little rubberiness
to it so you feel like you've chewed & eaten something worthwhile. ;-)

I apoloigze in advance to all the homosexual chefs that ruin lobsters &
crabs for high salaries.
