I know I know, there are other data packs which add recipe books for the brewing stand, so I'm not saying you should pick mine, but go ahead if you'd like. This data pack, as the name suggests, adds a brewing recipe book. You can obtain the book by sneaking and interacting with the brewing stand, which adds the book to your inventory, the instructions on how to use the book are written inside it. To get rid of the book you can toss it on the floor and it will be deleted automatically. This should work in multiplayer, though I have not tested it, but please inform me of any bugs or glitches you find.
