Step 1

Prepare a grill for high indirect heat (for a gas grill, leave one or two burners off; for a charcoal grill, bank coals on one side); oil grate. Bring pineapple juice, honey, vinegar, mustard, red pepper flakes, sesame oil, and turmeric to a simmer in a small saucepan over medium heat and cook, swirling occasionally, until reduced to ¾ cup, 10–15 minutes. Let cool. Transfer half of sauce to a small bowl and set aside for serving.

Step 2

Season pork with salt. Grill over direct heat until browned all over, about 3 minutes per side. Continue to grill, turning several times and basting with remaining sauce, until charred and coated with a thick layer of glaze, about 4 minutes. Move to cooler part of grill and take internal temperature of pork. If needed, continue grilling over indirect heat until an instant-read thermometer inserted into chops near bone registers 130°, 1–4 minutes more. Transfer pork chops to a wire rack and let rest 10 minutes before slicing. Serve with reserved sauce alongside.
