You might think a sandwich made with baguette bread is the most popular food in France. But think again. The French are going crazy for hamburgers. A new study shows that sales of American-style burgers have overtaken the sales of the traditional jambon-beurre baguettes the French ham and butter sandwich. Gira Conseil is a French restaurant marketing company. Its study says about 1.2 billion ham and butter sandwiches were sold in France in 2017. About 1.4 billion burgers were sold during the same period. Sales of both baguette sandwiches and hamburgers are on the rise, the study says. It notes that the ham and butter sandwich saw a 1.3 percent growth in 2017, while burger sales recorded a 9 percent increase last year. The study says that France’s favorite sandwich is slowly losing ground to the hamburger.
