I’m not in Texas but I’m joining in anyway. I love all sorts of Cajun food. For years I had ‘Paul Prudhomme’s Louisiana Kitchen’. I tried a couple recipes, was unimpressed & it sat on the shelf. My GF tried the Seafood File Gumbo recipe & it is fantastic. She makes it mostly in the winter & it’s terrific on a cold winter’s day. It’s as good a gumbo as I’ve had anywhere - right here in New Jersey.
You can buy File Powder online from Parsley Porch. It’s good & reasonable priced. Here’s the link: https://www.sites.google.com/site/parsleyporch/Home
