In a bowl, combine the warm water, salt, oil, and pre-cooked white cornmeal flour. Mix well and knead for two minutes with wet hands. Cover with a cloth and let it rest for 5 minutes.
Divide the dough into equal portions using wet hands (every 3/4 cup of white pre-cooked cornmeal will yield 4 arepas). Shape each portion into a ball, then flatten it out to form a disc. Use your fingers to round the edges. Wetting your hands prevents the dough from sticking to your fingers. The arepas should resemble hockey pucks but be a bit thinner.
Add oil to a pan and preheat for 90 seconds. Add the arepas and cook for 5 minutes on each side until golden.
