Using a large bowl pour water and add salt.
Gradually, add the corn flour until you have a smooth dough formed. Let it rest for 3 minutes.
Knead and separate dough into small balls. Press with your palms forming a large patty (disc) shape. You can pick the size you want them to be (thick, thin, large, mini, small, with a hole).
Baked version: place them into a griddle over medium heat with a bit of oil, and heat 5 minutes on each side. Place them in the oven and toast them for 10 minutes.
Deep fry version: Grab the patty shapes arepas and fry them using your favourite oil. Heat 4 to 5 minutes on each side and serve.
