In a bowl combine the corn flour and 1 cup on cheese.
Add the melted butter and slowly add about half of the milk and start incorporating until a dough forms.
Add the rest of the milk and continue kneading for about 5 minutes.
Let the dough rest, covered with a cooking towel for about 5 minutes.
Form tennis-size balls (about 50 grams each) and use a flat surface covered in cling wrap (as shown in pics) to flatten them. A tortilla press is an excellent tool to do this.
Use one of the rounds as the base and add the cubed ham and a handful of cheese (about 1 tablespoon each).
Cover with another dough round and press the edges until you form a seamless round patty.
Grease a cast iron skillet with the tablespoon of vegetable oil. I like to use avocado oil for its neutral flavor.
Cook the arepas in a cast iron skillet or non-stick pan over medium-low heat about 20 minutes per side until golden brown. They will form a crisp crust that will allow you to flip them easily.
Flip them carefully with a spatula and cook on the other side for another 15-20 minutes.
Serve and enjoy!
