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.
