When I saw your post that included the National Food Days, I noticed Coquilles St. Jacques and realized I had no idea what it was, so I looked it up online, and was delighted to know that it was a shrimp and scallop dish, since shrimp and scallops are my favorite kinds of seafood.
I am wondering if this is perhaps a name they use in the south or even in the New Orleans area (since it is obviously a French name), because I have never seen it on the menu at any restaurants here, but I have seen Shrimp and Scallop Thermador, which is basically the same thing.
I will go find my recipe for it and type it up and post it later today for everyone to enjoy.
I have only ever seen Coquille St Jacque as a scallop dish since coquille is the French word for scallop. I live and grew up in the South and have never seen it. A really really good recipe for it can be found in Anthony Bourdain’s Les Halles cookbook. My go to recipe and should be online easy.
