Gumbo! 
. We love Gumbo! Here are some pix of us cooking up a roux for a seafood gumbo a few year's ago.

When we want to do a gumbo in a hurry, without making roux from scratch, we've tried a few packaged products. For years, we've liked Bayou Magic's products
www.bayoumagic.com/, but recently the gumbo base has become too salty for our tastes. Tonite we tried a new product, Cajun C.J.s

A dark roux, seasoned well. This was for a chicken and andouille gumbo.
In SoWal, I believe Shrimper's has frozen andouille (maybe tasso,too) and I think Destin Ice might have andouillie as well.
