Treatise on Make-Up and Jam, which is exactly what it sounds like: a cookbook full of jam recipes. "And the jelly will become one with the cream of peanut, and the bread will rejoice, for it is made delicious." "Nostradamus' jams were apparently so yummy that the book managed to become a best-seller in 1555, back when like five people knew how to read. It even became the standard on how to make jamby the jam makers in Paris. Nostradamus gathered all these recipes way before going into the future-guessing business, when he was an aimless 20-something going around Europe researching herbal medicines (he listened to a lot of Frank Zappa and grew his hair long during this time)". "The book also included recipes for other delicious treats like candy, marzipan, and toothpaste. However, this was still a book by Nostradamus, so naturally there's plenty of b.s. in there. One recipe claimed to be able to cure the plague. Another could turn your hair blonde. So, yeah, maybe the whole best-seller thing had less to do with the jams being delicious and more with their plague-curing powers".
