It's my understanding that Opah isn't easy to come by, so I was thrilled when I found some. Then I discovered that there are not many recipes out on the internet, so recipes are also hard to come by. I found this one and we loved both the fish and the recipe. I also had to search for a recipe for the Tomato Concasse, so included it here for convenience. Just as a note, I didn't use nearly as much butter as the recipe calls for. From Chef Linda Yamada of the Beach House in Hawaii.
