Pork Osso Buco - cooking recipe

Ingredients

salt and freshly ground black pepper to taste
6 thick-cut pork shank sections, 2 to 3 inches thick
1 tablespoon olive oil
1 tablespoon butter
1 large yellow onion, diced
1 large carrot, diced
2 ribs celery, diced
1 teaspoon kosher salt
1/4 cup tomato paste
2 tablespoons all-purpose flour
1 cup white wine
2 cups chicken broth
1 bay leaf
1/2 teaspoon dried thyme
1/2 teaspoon dried rosemary
1/8 teaspoon ground cloves
Chopped Italian parsley
Freshly grated lemon zest

Preparation

Salt and pepper both sides of pork shank sections.
Heat oil and butter in a heavy pot over high heat. Brown pork until it gets a nice sear, 3 or 4 minutes per side. Transfer pork to a plate; reduce heat to medium. Add onions, carrots, and celery to pot. Sprinkle with salt. Cook and stir until onions start to turn translucent. Add tomato paste; cook and stir until tomato paste starts to caramelize, about 2 minutes. Sprinkle in flour; stir for 2 minutes. Add white wine and raise heat to medium high.
When sauce comes to a simmer, cook until sauce reduces slightly. Add bay leaf, thyme, rosemary, and ground cloves. Add chicken stock and return to a simmer. Transfer pork back to pot along with any accumulated juices. Bring mixture to a very slow simmer. Cover and cook until fork tender, 3 to 3 1/2 hours.
Serve shanks with plenty of sauce, topped with freshly chopped parsley and a sprinkle of lemon zest.
