INGREDIENTS
2 bone-in pork rib chops, preferably blade-end, 1 1/2 inches thick (12 to 16 ounces each)
2 tablespoons kosher salt
1 1/2 teaspoons sugar
Freshly ground black pepper
2 tablespoons vegetable oil
2 tablespoons butter
1 medium shallot, thinly sliced
8 sprigs fresh thyme

DIRECTIONS
1.
Pat pork chops dry with a paper towel. Combine salt and sugar in a small bowl. Season pork chops generously on all sides with salt/sugar mixture. Transfer to a wire rack set in a rimmed baking sheet and refrigerate, uncovered, at least 8 hours and up to 24.

2.
The next day, preheat oven to 250°F. Place baking sheet with pork chops in oven and cook until an instant read thermometer inserted into the center of the chops registers 100 to 110°F on for medium-rare, about 30 minutes, or 110 to 120°F for medium, about 35 minutes. To prevent overcooking, start checking temperature 5 to 10 minutes before suggested time. Remove from oven.

3.
Heat oil in a large stainless steel or cast iron skillet over high heat heat until smoking. Place pork chops in skillet and cook, turning occasionally, until starting to brown, about 1 1/2 minutes. Add butter, shallots, and thyme to skillet. Continue cooking, spooning shallots and thyme on top of chops and basting with butter until golden brown on both sides and well-crusted, about 2 minutes longer. Stack pork chops with tongs, hold them on their sides, and sear the fat caps on the edges until crisp, about a minute. Remove pan from heat, transfer chops to a clean rack set in a rimmed baking sheet, and let rest for 3 to 5 minutes.

4.
Just before serving, reheat dripping in pan until smoking. Pour hot drippings over chops. They should sizzle and crisp a bit. Serve immediately.
