Colombian Beef and Potato Empanadas

Colombian empanadas are typically quite small — a couple of bites each — and have a crisp corn crust. There are a wide range of fillings you’ll find across Colombia, but this meat-and-potato mixture is the most common. Small yellow potatoes called papas criollas are the potato of choice here, but they are nearly impossible to find in the United States, so I use Yukon Gold instead. My wife’s family typically keeps the seasonings simple — salt, pepper and a dash of paprika — though many recipes include cumin or Triguisar, a powdered seasoning mix that contains ground cumin, paprika, achiote, turmeric and garlic. I season my filling with a little chicken bouillon, but you could use plain salt instead. The filling uses half an onion and half a tomato, so save the other half for the fresh, cilantro-based ají, to serve with the empanadas.

Ingredients

• 1

  medium Yukon Gold potato (about 6 ounces), peeled and cut into 1/2-inch cubes (1 heaping cup)

• Kosher salt and freshly ground black pepper

• ½

  ripe beefsteak tomato

• 1

  tablespoon vegetable oil

• ½

  pound lean ground beef or pork

• ½

  small white or yellow onion, finely minced

• 1

  scallion, finely minced

• ½

  teaspoon sweet paprika

• ½

  teaspoon granulated chicken bouillon, plus more as needed (optional)

Preparation

1. Prepare the filling: Place potato cubes in a medium saucepan, cover with water and season with 1 teaspoon salt. Bring to a boil, reduce to a simmer, and cook until cubes are completely tender, about 10 minutes. Drain and transfer to a medium bowl. Set aside.
2. Meanwhile, using a flat palm, press the cut side of the tomato against the large holes of a box grater and grate the tomato until you’re left with just the skin. (The skin should protect your hand from the grater.) Discard the skin, then transfer the tomato and any juices to a small bowl. Set aside.
3. In a 10- to 12-inch skillet over medium-high, heat vegetable oil until shimmering. Add beef or pork, and cook, breaking it up with a wooden spoon until the pieces are quite small and completely cooked through, about 5 minutes. 
4. Add onion, scallion, paprika, bouillon (if using), and a few grinds of black pepper, and cook, stirring, until the onion is softened but not browned, about 1 minute. Immediately add the grated tomato and its juices, and cook, stirring, until the mixture is quite dry, about 5 minutes.
5. Transfer meat mixture to the bowl with potatoes and stir together with a fork, letting the potato get roughly mashed up. (The filling should form cohesive balls when gently packed.) Taste and adjust seasoning with more salt, bouillon and pepper to taste. Allow to cool completely. Spreading it out on a large plate or tray and placing it in the fridge will speed up this process.
6. Assemble the empanadas: Divide masa into 24 golf-ball-size balls. Working one ball at a time, place inside a plastic zip-top bag and press down with the bottom of a skillet to form a circle about 3 inches in diameter. Carefully remove from the bag and transfer to a clean cutting board or tray. Repeat with remaining dough balls, laying them out side by side. Cover the disks with a clean, lightly damp kitchen towel.
7. Working one empanada at a time, place about 2 teaspoons of meat mixture in the center of the disk. Lift the front and back edges and seal them at the top by gently pushing them together. Seal the empanada, working from the center outward until both ends are completely sealed. Gently curve the empanada to form a slight crescent with the sealed edge at the top. Repeat with remaining empanadas.
8. In a large Dutch oven or wok over high, heat 2 quarts oil until it registers 375 degrees on an instant-read or frying thermometer. Using a metal spider or slotted spoon, lower empanadas into the hot oil one at a time. You should be able to cook about six empanadas per batch. Cook empanadas, adjusting heat to maintain an oil temperature of 325 to 375 degrees, until empanadas are crisp and golden, about 3 minutes. Using a slotted spoon or metal spider, transfer empanadas to a paper-towel-lined plate or bowl and immediately season with salt.
9. Serve empanadas hot, with a bowl of ají and a spoon to drizzle the sauce over the empanadas and into them as you eat.
