And that was my point ... back in the 60's, the average native New Orleanian wouldn't pay to eat "Coonass" food in a restaurant. It was considered much too déclassé to be commercially viable.
I have all of the
River Roads cookbooks, and my original one (THE original one; I got it from an Aunt who was given the first edition when it came out in 1959) has a section called "How Men Cook" -- the good ladies of the BTR Junior League segregated all the game recipes into that section, as if it was permissible to eat the stuff when at the Camp, but not in the house, LOL. Lafayette's
Talk About Good didn't go quite that far in 1967; it just has a separate section for Game. (I collect community cookbooks from the South, I have dozens of them from all over, but naturally, I have more from Louisiana than anywhere else.)
I think that when most people not from there think in terms of "classic" Cajun food, they think seafood, or crawfish at the least, and that's very true in the parishes closest to the Gulf and the Atchafalaya Basin, because those folks live on the water. However, as you and I both know, there are a lot of Cajuns who live further inland, and those folks did not traditionally eat as much seafood; back when you had to use a horse (or your feet) to get there, it was a danged long way from Mamou to Delcambre (heck, it still takes an hour and a half by road, not counting traffic in Lafayette.) Those folks ate a lot of chicken and pig and field greens, both wild and domestic, along with game, and thus you have the genesis of the food served at Cochon.
BTW, everyone I know who makes cinnamon pickles makes them with watermelon; I always thought that was the standard recipe.
