We had a few leftover Cape Cod lobsters from our birthday party (because many of the gals could only handle half a lobster). With these critters over one and a half pounds, I like to split them with a cleaver and a mallet, and guests like it that way.
I hit the jackpot with these three - all gal lobsters with abundant delicious roe. I like to eat that green liver too. Tasty.
In Maine, they call lobsters "bugs."
Even if you do not love lobster, it's a festive food. Lobster-buying tip: the meat-weight ratio increases with increasing lobster weight. Bigger lobsters are thus always a better deal. Somebody could do the math. Big lobsters are no more chewy than smaller ones.
Our lobster place in Wellfleet had an 8-pounder and a ten-pounder. Seafood stores will always steam them for you without charge.
Another comment about lobster fishing: government regulations determine keepable sizes and, in government's wisdom, it's ass-backwards just as it is with Striped Bass. Best for the species for fishers to keep the smaller ones, few of whom will ever reach breeding age anyway, and not keep the big breeders. But that makes too much sense.
