Cook's book is a cooking tool used to make food from recipes. All of the recipes are processed foods and don't require heat to make, or already cooked without using any heat.
The first free page can be obtained from the Cook's assistant quest. To unlock further recipe pages, players need to pay an extra fee which rises with every new page to unlock.

List of all recipes[]
Notes: The purpose of comparison between the total energy from raw edible ingredients and the energy from recipes is to find the most effective food recipes. Therefore, the total energy is calculated by alternative food recipes (if possible) and not the entire raw ingredients. For example, the total energy from ingredients for a Carrot Cake is one Carrot Soup and one Cake, not 20 Carrots. Pizza will be 1 Tomato Soup and 5 Cheese.
The table is also useful to help you decide on food that use the same ingredients. Carrot Cake for example only gives 8% more energy for the ingredients that can be used for 1 Carrot Soup and 1 Cake, not even considering the chance of getting it burned before you have a Runite oven. Therefore, it's only worth to cook when burn rate is 0%. However, since all cake recipes use egg as an ingredient, which is hard to come by, it's not always worth it to make all types of cakes, especially compared to Pancakes which also use egg to make.
Pizza gives 65% more energy than alternative food, which means it's worth to cook when burn rate is 30% or lower (Silver oven or better).
Similarly, Snapegrass Stew is generally not worth to make because of the long growing time of Snapegrass seeds.
