Remove the membrane from the rack of spareribs, then cut into individual ribs. Place the ribs in a large resealable bag.
Whisk to combine the hoisin sauce, soy sauce, dark brown sugar, rice vinegar, ketchup, sriracha, ginger, Chinese five-spice, red gel food coloring and garlic in a medium bowl. Reserve 1/2 cup of the marinade and pour the remaining marinade into the bag with the ribs. Seal the bag and massage to coat the ribs with the marinade. Place the bag on a small baking sheet or plate and refrigerate for 4 to 6 hours and up to overnight.
Preheat the oven to 325 degrees F.
Line a baking sheet with aluminum foil. Remove the ribs from the marinade and discard the liquid. Place the ribs in a single layer on the prepared baking sheet, cover tightly with foil and bake for 1 hour 30 minutes. Remove the foil and continue baking, brushing with the reserved marinade every 10 to 15 minutes, until cooked through and well browned, 40 to 50 minutes more.
Transfer to a serving platter and garnish with sesame seeds, scallions and lime wedges.
