What are kolaces, spaetzle and pierogies? Most of don't give a second thought about the wealth of history and culture that shapes our dining habits and taste preferences. Our recipes, menus, ceremonies, and etiquette are directly shaped by our country’s rich immigrant experience, the history and innovations of food preparation technology, and the ever-changing availability of key ingredients. Through a selection of artifacts, photographs, and illustrations, Key Ingredients examines the evolution of the American kitchen and how food industries have responded to the technological innovations that have enabled Americans to choose an ever-wider variety of frozen, prepared, and fresh foods. Key Ingredients also looks beyond the home to restaurants, diners, and celebrations that help build a sense of community through food.
