Alchemy recipe
From Dragon Quest Wiki
An alchemy recipe is a set of instructions for how to make a specific item using alchemy. They can be located in various locations in games which have an alchemy system. Not all items which can be made using alchemy will necessarily have an explicit recipe which the player can find. Some recipes are considered "secret" and must be discovered either by experimentation or by learning it using an external source (online, strategy guide, etc).
