Known in Cantonese as Kam Chin Beng, this moreish snack is sold at a little makeshift stall near the big fountain in the middle of Macau's Senado Square. It's a one-man show, whereby the hawker deftly rolls and flattens little balls of dough on a hot griddle and cooks them till they're golden-brown. The crisp of these delectable babies endures through the day and even until the next morning!
