Sharp microwaves do not come with separate cookbooks. Some user manuals for older models do offer a few recipes in the back of the book.
Sharp does sell its own cookbook. The company first published the "Sharp Microwave Carousel Cookbook" in the 1970s, and it has published a series of later editions. The book contains color photos, step-by-step instructions and information on special cooking techniques. Customers can order the latest edition of the cookbook directly from Sharp, with ordering information available in the microwave instruction guide that comes with new microwaves. Used bookstores might carry older editions of the cookbook.
