As the resident Venezuelan at IRLF, I believe I can call myself an expert on Arepas. I have eaten them my entire life for breakfast, lunch, afternoon snack, dinner, late night bite, and any other time of the day. Arepas are really like sandwiches or tacos, fairly easy to make, and you can put whatever you want in them. If your fridge is completely bare and you just have some butter, ham and cheese, that's perfectly fine and just how we eat it every morning.
First you need to buy a package of this:
This can be found at some supermarkets like Stop n' Shop, Mexican, Dominican, Puerto Rican, and Latino markets. This is the core part of the arepa, without it you have nothing.
Next Step:
2 1/2 cups of luke warm water (it really does need to be luke warm, if it's too cold then the dough will be all wrong)
2 cups of P.A.A. Corn Meal
1 teaspoon of salt (I also like to add a dash of sugar)
Then:
Pour water into a bowl, add the salt (and sugar if you like), and slowly add the cornmeal while whisking it, until it becomes too hard to whisk.
Now comes the fun part:
Get your hands in there and start kneading the dough until it becomes nice and smooth (make sure you wash your hands first).
When it's completely smooth, start making balls from the dough, they can be whatever size you like, and however many you want.
Now, take this balls and pretend your making hamburger patties. They can be thick or skinny, it's really up to you.
(If you have dough left over, no worries, just store it in the fridge for later. When you come back to it, it might be a little hard, just add a little bit of luke warm water and you should be good to go.)
Cooking them:
Butter and heat up a skillet at low heat, and place the uncooked arepas.
When they get this nice brownish color on one side, flip them over and cover, maintaining the low heat.
They should be ready in about 6-10 minutes.
When they're ready, you could wrap them in any towel you have lying around the kitchen just to make them a little softer. This isn't necessary, but it doesn't hurt.
When they've cooled down a bit, take a butter knife and cut the arepas like so,
and stuff them with whatever your heart desires.
Enjoy!
