I don't remember when I learned about seed cake, but I do know that it was years before I actually tasted it. It sounded so interesting, but no one in my circle had ever heard of it. I've been making it for years now, and I've never tired of its simple but intriguing taste. It's basically just a very rich biscuit dough flavored with caraway seed. I generally add orange or lemon zest to the dough. A newly made one has a half life of about a day here.
