Crisp Lettuce

Crisp lettuce, commonly associated with iceberg varieties, rose to prominence in the United States in the early 20th century as refrigerated rail transport made it widely accessible. Originally cultivated in ancient Egypt as a wild lettuce species, it evolved over centuries into more structured, compact heads through selective breeding. Its crisp texture and long shelf life made it a staple in American households, diners, and fast-casual cuisine. While once considered less nutrient-dense than darker greens, it has remained culturally significant due to its versatility and role in classic dishes like wedge salads and burgers. Today, crisp lettuce continues to bridge convenience and freshness in both traditional and modern culinary applications.
