I'll never forget where I had my first Louisiana-style crawfish pistolette. They had them at an Exxon gas station on the side of 190 in Port Barre, LA, and now I get them every time I head to Baton Rouge or New Orleans!
The Summer of 2023 was record-breaking, but the heat didn't just affect utility bills. It may adversely impact the upcoming crawfish season in Louisiana.
If you buy crawfish from an actual retailer, chances are they have been purged, and are going to be great when cooked correctly. The vein isn't going to matter. Don't let it slow you down!
Never, ever, ever, under any circumstances buy crawfish or shrimp or any other seafood for that matter from China. You won't believe what they do to their food!
