Pan-Fried Stuffed Potatoes (Cuban Papas Rellenas)

1. Stage

Heat a large skillet over medium-high heat. Cook and stir ground beef with onions and garlic in the hot skillet until beef is browned and crumbly, 5 to 7 minutes. Drain and discard grease. Turn heat down to medium-low. Add tomato sauce and wine and let simmer. Stir in olives. Season with salt and pepper; adjust the seasonings per taste.

2. Stage

Place potatoes into a large pot and cover with salted water; bring to a boil. Reduce heat to medium-low and simmer until tender, about 20 minutes. Drain and mash potatoes, then set aside to cool.

3. Stage

Separate the egg yolks from the whites into two bowls. Mix the egg yolks into the cooled mashed potato mixture. Whisk the egg whites for 1 minute.

4. Stage

Take 1/4 cup of the mashed potatoes and form into a ball. Make a dent in the ball, to give it more of a bowl shape. Fill the indentation with 1 tablespoon of the meat mixture, and then reseal it.

5. Stage

Reshape the potato as a ball again. Dip the ball in the egg whites, then roll the ball around in bread crumbs until coated. Repeat with remaining potato and meat mixture. For a better coating, or for a crunchier texture, you may dip the ball into the egg whites again and coat it with another layer of bread crumbs. Refrigerate the potato balls for at least 4 hours before frying.

6. Stage

Pour enough oil into a skillet or frying pan to cover half of the potato balls. Heat oil to 350 degrees F (175 degrees C).

7. Stage

Working in batches, place several balls into the frying pan and cook on each side until golden brown, 2 to 3 minutes, taking care not to overcook. Drain the stuffed potatoes in a single layer on paper towels.
