Step 1

Shred 3 ounces of the mozzarella and cut remaining 5 ounces into 1/2-inch cubes. Transfer shredded cheese to a large bowl and cubed cheese to a medium bowl.

Step 2

Add cornmeal, 1 teaspoon salt, and warm water to the shredded cheese and mix to combine. Set aside for 10 minutes to allow cornmeal to absorb liquid. The mixture should resemble soft Play-Doh.

Step 3

Preheat the oven to 200 degrees F (95 degrees C).

Step 4

With damp palms and fingers, place 1/4 cup arepa mixture into your palm and flatten into a 2 1/2-inch disk. Place 3 to 4 cubes of the mozzarella into the center. Gently fold edges of dough over to cover mozzarella cubes completely, patting to form a cake. Repeat until all dough and cheese has been used.

Step 5

Heat 1 tablespoon oil in a large nonstick skillet over medium heat. Add 3 or 4 arepas and cook until both sides are golden brown and charred in spots, 4 to 5 minutes per side. Remove to a parchment-lined baking sheet and season with a pinch of the remaining salt. Place in the preheated oven to keep warm. Repeat with remaining oil, arepas, and salt.
