several editions, including English versions. These include The Art of Caribbean Cookery - Doubleday, 1957; Puerto Rican Cookery - Pelican Publishing, 1983; and, Juntos en la Cocina (co-authored with her husband, Luis F. Valldejuli) - Pelican Publishing, 1986. Professional cookbooks Professional cookbooks are designed for the use of working chefs and culinary students and sometimes double as textbooks for culinary schools. Such books deal not only in recipes and techniques, but often service and kitchen workflow matters. Many such books deal in substantially larger quantities than home cookbooks, such as making sauces by the liter or preparing dishes for large numbers of people in a catering setting. While the most famous of such books today are books like Le guide culinaire by Escoffier or The Professional Chef by the Culinary Institute of America, such books go at least back to medieval times, represented then by works such as Taillevent's Viandier and Chiquart d'Amiço's Du fait de cuisine. Single-subject Single-subject books, usually dealing with a specific ingredient, technique, class of dishes or target group (e.g. for kids), are quite common as well. Jack Monroe for example features low budget recipes. Some imprints such as Chronicle Books have specialized in this sort of book, with books on dishes like curries, pizza, and simplified ethnic food. Popular subjects for narrow-subject books on technique include grilling/barbecue, baking, outdoor cooking, and even recipe cloning (Recipe cloning is copying commercial recipes where the original is a trade secret). Community Community cookbooks (also known as compiled, regional, charitable, and fund-raising cookbooks) are a unique genre of culinary literature. Community cookbooks focus on home cooking, often documenting regional, ethnic, family, and societal traditions, as well as local history. Sondra Gotlieb, for example, wrote her cookbooks on Canadian food culture by visiting people and homes by region. She gathered recipes, observed the foodways, observed the people and their traditions of each region by being in their own homes. Gotlieb did this so that she could put together a comprehensive cookbook based on the communities and individuals that make up Canada. Gooseberry Patch has been publishing community-style cookbooks since 1992 and built their brand on this community. Community cookbooks have sometimes been created to offer a counter-narrative of historical events or sustain a community through difficult times. The Historical Cookbook of the American Negro, published in 1958 by the National Council of Negro Women, includes recipes that illuminate histories of
