Preheat the oven to 350°F. Mix salt, coriander, brown sugar, and piment d'Espelette in a small bowl.
Place the ribs on a double layer of aluminum foil, large enough to wrap them fully. Rub the spice mixture all over the ribs.
In a small bowl, mix molasses and apple cider vinegar. Brush this mixture onto both sides of the ribs.
Wrap the ribs tightly in the foil and place on a sheet pan. Bake for 2 hours, until tender.
While the ribs cook, make the glaze: In a skillet, simmer apple cider vinegar, molasses, cane syrup, Creole mustard, serrano, black pepper, and salt. Add peaches and cook until softened and the glaze thickens.
Remove ribs from the oven, increase heat to 400°F, and open the foil. Drain any juices, pour the glaze over the ribs, and bake uncovered for 5-10 minutes until caramelized. Enjoy!
