Crispy on the outside and tender on the inside, these fried croquettes made with braised beef make great party appetizers. This recipe is adapted from Tasting Rome: Fresh Flavors and Forgotten Recipes From an Ancient City by Katie Parla and Kristina Gill.
- 1 lb. beef shin, trimmed
- Kosher salt
- 1 cup dry white wine
- 10 whole black peppercorns
- 3 carrots, peeled and halved
- 2 medium yellow onions, quartered
- 2 whole cloves
- 1 large potato
- 3 1⁄2 oz. mortadella, thinly sliced
- 1⁄3 cup grated Parmigiano-Reggiano
- 2 tbsp. finely chopped flat-leaf parsley
- 4 large eggs, lightly beaten
- 1 cup all-purpose flour
- 1 cup fine breadcrumbs
- Vegetable oil, for frying
Salt the beef, cover it with plastic wrap, and refrigerate it overnight.
The next day, in a medium saucepan, cover the beef with 6 cups water. Add the wine, the peppercorns, carrots, onions, and cloves and bring to a boil. Reduce the heat to maintain a simmer and cook until the beef is tender, 1 1⁄2 to 2 hours. Transfer the meat to a plate and shred it with tongs or two forks and transfer it to a food processor. Strain the broth through a fine mesh sieve over a bowl and discard the solids.
Meanwhile, in a small saucepan, boil the potato until tender, about 40 minutes. Transfer to a bowl and, when cool enough to handle, peel and cut into 1-inch pieces. Add the potato and mortadella along with 1 to 2 tablespoons of the reserved broth to the food processor and pulse until it forms a paste. Transfer to a medium bowl along with the Parmigiano-Reggiano, parsley, and half of the eggs. Season with salt and pepper and mix well to combine. Refrigerate 1 hour.
Remove the beef from the refrigerator and form into 16 patties, about 2 1⁄2-inches wide and 1⁄2-inch thick. Heat 2-inches vegetable oil in a 6-qt. saucepan until a deep-fry thermometer reads 350°. Place flour, remaining eggs, and bread crumbs in separate shallow dishes. Working with 1 patty at a time, dredge in flour, dip in eggs, and coat in bread crumbs. Working in batches, fry patties until golden and crisp, 3 to 4 minutes. Transfer patties to paper towels to drain and serve hot.
