I think you can also make boudin patties with no need for casings.

I love boudin and buy it whenever I see it which isn’t that often.

Or, I buy it from Poches.  I like their seasoning the best.

 
Poche’s boudin is good but their real strength is their meat n 3 cafeteria line. We always stop there on the way to NOLA to load up some big plates and sit in their taxidermy lounge.
