2Toasted marshmallows stuffed with raisins? Green-and-white luncheons? Chemistry in the kitchen? This entertaining and erudite social history, now in its fourth paperback edition, tells the remarkable story of America's transformation from a nation of honest appetites into an obedient market for instant mashed potatoes. In Perfection Salad, Laura Shapiro investigates a band of passionate but ladylike reformers at the turn of the twentieth century--including Fannie Farmer of the Boston Cooking School--who were determined to modernize the American diet through a scientific approach to cooking. Shapiro's fascinating tale shows why we think the way we do about food today.
