There are millions of cookbooks but only one remains relevant after nearly 90 years. Irma S. Rombauer's Joy of Cooking has been a staple in American kitchens for decades — even laying the foundation for greats like Julia Child. Featuring the publication's 2006 edition, its 4,500 recipes are bound in black Vachetta leather and gilded with hand-painted edges. An embossed title keeps the aesthetics tight, creating a modern housing for the cooking classics.
