Arepas are very popular in Latin America. I discovered it thanks to a friend from Colombia and I can tell you that her mom makes them great!
It is very easy to make: corn flour (I used white from PAN), water and salt. You can eat them in many ways: with queso blanco like on the photo, or with chicken, ground beef, tomatoes, avocado...There are many ways. Just consider this as a bread!
In New York, I like two restaurants for Arepas, both Venezuelan:
located in the East Village.
