Ever been to a restaurant, and you see something imaginary on the menu—roasted Jabberwock, say, or braised Ent with balsamic vinaigrette—and you don’t know if you can order it or not because you don’t know if it’s kosher? Now, there’s a new book that will tell you: The Kosher Guide to Imaginary Animals.
Basically, Ann and Jeff VanderMeer have done extensive research (no, but really) into both fictional creatures and the laws of kashrut to determine whether 34 imaginary animals are kosher or not. Only seven are, including the biblical Behemoth, Leviathan, and Ziz. (Jewcy took a look at a few of these as well a couple months ago.)
Oh, and if you want to learn a bit more about mythical animals from Jewish folklore—presumably they are more likely not to be trayf, right?—Tablet Magazine had the skinny on several last Halloween.
