I have had it a couple of times. We got them at a local Cajun market/restaurant here.
We all liked it. Different. Kinda pricey, but worth it I think. But no, I would not buy one from anywhere except a Cajun place, they know their stuff when it comes to seasoning and cooking.
It’s a speciality item even for that place, something not always available. But, holiday time comes around and the place takes orders like crazy.
