So, since the Saints are in the Superbowl this year, I'm going all Louisiana for my Superbowl party - crawfish etoufee, shrimp and andouille gumbo, red beans and rice, etc.

A few years ago, I was able to buy frozen crawfish tails here in Tucson, but now it seems like I can't get them anywhere, which makes me sad.

What can I use as a substitute? I don't want to use shrimp, but my local TJ's carries langostino tails, would that work? Thanks in advance.
