1 lb. (3 1/3 cup) Harina P.A.N. (pre-cooked corn flour, other brands are Maseca or Masarepa can work too)
1 Tblsp salt
2 Tblsp vegetable shortening
4 cups of warm water
Using a mixer, add all ingredients and mix for 2 minutes until completely combined and smooth.
Keep dough covered with a moist towel and let dough rest for 10 minutes. Once rested, portion dough into a 6oz ball and flatten it as if making a burger patty or hockey puck. The arepa needs to be thick enough that it can be sliced and stuffed like a pocket. An approximate size is about 1/2" thick and 4 1/2" diameter. Set all arepa o a sheet tray.
To cook, you can put on a grill pan that has been oiled and preheated for about 5-8 minutes on each side until crisp. Or you can put in oven at 350 for 10-15 minutes. Using a small serrated knife, slice through the middle halfway, making sure that the bottom part is not sliced open. Stuff generously with your favorite filling and serve immediately. EnJOY!
