In Foldit, the Cookbook is where recipes are stored. (The cookbook is not available in Intro Puzzles.) Recipes are one of the most important features of Foldit. Recipes can perform simple tasks like shake and wiggle, and they can also automate complex tasks like rebuild and remix. Some recipes end quickly, others may run for days, and some are designed to run in an "infinite loop" until you cancel them. The Foldit website has a recipes section, with a huge collection of recipes contributed by Foldit players over the years.
