Tortilla Chip Day is a holiday dedicated to the ultimate dip chip. Tortilla Chips are chips made from cutting tortillas into triangular pieces and then baking or frying them. They were probably made in Mexico for a long time, but they were first popularized and mass produced in Los Angeles in the 1950s by Rebecca Webb Carranza, who owned a tortilla making business with her husband. She wanted to find a use for tortillas that were not round enough to sell, so she turned them into chips and began selling them to wide audience. Now Tortilla chips are sold in almost every Mexican restaurant in the United States. They are a constant staple of Mexican cuisine.
