Cookbook
The Cookbook is a special item in the Paper Mario series. It gives a chef the ability to combine various items, creating new items in the process as a discovered recipe.
It was first seen in Paper Mario, in which the book was found in the Shy Guy's Toy Box, stolen by a Shy Guy during the events of Chapter 4. When Mario gives the Gourmet Guy the Cake, the Gourmet Guy will be glad and crazy as he rockets out the area, dropping the Cookbook. When Mario gives the Cookbook to Tayce T., she will let Mario cook not but one item but two items to make a combined recipe. (However, the Frying Pan was also needed for her new abilities to be used).
In Paper Mario: The Thousand-Year Door, it was hidden in the Creepy Steeple and is the work of the famous chef, Maitre Delish. To obtain this Cookbook, Mario must roll into a tube and enter a small hole near the entrance of the Steeple. It was given to Zess T. during the "Seeking Legendary Book!" trouble.
