I don't mean to sound flippant, but when I crave fish, it's really the malt vinegar they used to serve with it that I'm really craving. I'm learning that exploring herbs and spices goes a long way toward keeping me interested in food. Flavor is important. Most of my life, I heard that song, "Parsley, sage, rosemary, and tyme," but only recently discovered what tyme tastes like. I love it! Sage too. I'm gluten-free too, so I know how that complicates things. Are you getting enough iodine?
