I have read elsewhere that this recipe can be found in sunken chests obtained by fishing in Stillmoor, Shimmersand and Ember Isle. Using a half dozen Timed Trophy Lures, I fished up about 10 sunken chests. I did get two Eel Fillet recipes, a Snapper Jerky recipe, and a Rare Artifact Attractor recipe, but the Jellied Ray recipe still eludes me. I've spent many hours fishing up fish to make lures and using them. I have seen neither the recipe or even a sample meal on the AH and this is the last food I need for the Gourmand achievement. How frustrating!
