When a brand has accumulated as much recognition as the Big Mac — a burger McDonald’s has marketed to consumers in more than 100 countries — tinkering with it may be the last thing you’d want to do, but this is exactly what the Golden Arches has planned as it tries to sustain a sales turnaround.
For a few weeks in early 2017, the burger chain will offer two new versions of the iconic sandwich, which uses two all-beef patties, special sauce, lettuce, cheese, pickles, onions – on a sesame seed bun, in restaurants across the US. The miniaturized Big Mac, named the “Mac Jr.,” uses one 1/6 lb. patty, while the beefed up “Grand Mac” uses two 1/6 lb. patties. A classic Big Mac has two 1/10 lb. burgers.
