I have always thought crawfish were overrated for the money, taste and/or the hassle of live. Like eating Chesapeake Bay blue crabs, taste great, but too much work. Could stand there all day picking crabs and sucking crawfish and never get full! That's what the potatoes and corn is for...I know, but just sayin'. I would much rather have crab than crawfish though, flavor wise. I love crab legs but hate picking them too. I've bought snow crab legs and pre-picked the meat and found that by weight, I could have bought a pound of lump crab for the same money and save all that work! Slightly different flavor but all good.
I want to do a LCB this year too. Been saying that for years ever since I got my Butterball turkey fryer which will also double as a boiler/steamer. Got to think it through though. Everything is so expensive but thats not the only challenge...to me cooking everything exactly right is the challenge and I like sausage to be browned, so I would probably throw those in after grilling. Getting the seafood perfect looks like a challenge to me. Last thing you want to do is spend a bunch of money on good seafood and over-steam it. I mean, clams, oysters and mussles are perfect the minute their shell opens while shrimp is very exact on cooking time to be perfect. My guess is a lot of people are eating overcooked seafood with these boils. But its so cool as a presentation, nobody is going to say anything to the chef that prepares it except "excellent"!
