Arepas, a Latino treat you can find in Hong Kong
Susan Jung savours street-food snack that's basically a corn cake that comes thin or thick, fried or griddled, plain, topped or filled

At its most basic, an arepa is a flat cake made from ground dried corn, but it can take many forms. It's either fried or griddled; can be thin or thick; and it can be served plain, topped with other ingredients, folded over a filling, or split in half horizontally and stuffed. Sometimes, the raw dough is shaped around a filling before being cooked.
Typical toppings or fillings include grated cheese (the kind that melts in the heat and becomes oozy and stretchy), cooked meats, beans, egg, avocado and salsa; some vendors have a range of sauces that can be drizzled over the arepa, although - as it's often eaten out of hand - that can make things messy. In restaurants, it's easier to eat them with a knife and fork.
