Step 1

Place meat in a large mixing bowl. Sprinkle all sides generously with 1 tablespoon kosher salt.

Step 2

Place chopped garlic and a pinch of salt in a mortar and mash with pestle until pastelike. Add tomato paste; mash until blended. Transfer mixture into bowl with beef and rub onto all sides of meat. Add crushed peppercorns and ground pepper. Distribute evenly over all sides of beef. Transfer to a deep skillet or Dutch oven bone side down. Tuck sage leaves, rosemary, and dry bay leaves between pieces of meat. Carefully add wine along the side of the pan to avoid washing over the top of the meat.

Step 3

Place pan over high heat and bring to a simmer; reduce heat to low. Cover tightly. Cook until meat is fork tender, turning pieces every 30 minutes or so, about 3 1/2 hours. Transfer pieces of meat to a warm bowl.

Step 4

Increase heat to high and bring braising liquid to a boil. Simmer until liquid is reduced by about half or until slightly thickened, 8 to 10 minutes. Remove bones from meat.

Step 5

When sauce is thickened, transfer meat back to skillet. Reduce heat to medium-low and spoon sauce over meat. Cook until until heated through, about 5 minutes.
