- Marinade:
- 6 ounces pineapple juice
- 1/2 cup hoisin sauce
- 1 teaspoon hot chile paste (such as sambal oelek)
- 1 rack pork spareribs, cut in half
- Dry Rub:
- 2 tablespoons fine sea salt
- 1 tablespoon brown sugar
- 1/2 teaspoon Chinese five-spice powder
- 1 pinch cayenne pepper
- Baste:
- 1/2 cup ketchup
- 1/4 cup seasoned rice vinegar
- 2 tablespoons hoisin sauce
- 1 tablespoon soy sauce
- 1 tablespoon fish sauce
- Whisk pineapple juice, 1/2 cup hoisin sauce, and hot chile paste together in a bowl; pour marinade into a resealable plastic bag. Add spareribs, coat with marinade, squeeze out excess air, and seal the bag. Marinate in the refrigerator, 8 hours to overnight.
- Preheat oven to 300 degrees F (150 degrees C). Line a baking sheet with a silicone baking mat.
- Remove spareribs from the marinade and shake off excess; discard remaining marinade. Pat ribs dry and place on the prepared baking sheet.
- Whisk sea salt, brown sugar, Chinese five-spice powder, and cayenne pepper together in a bowl. Season ribs with dry rub.
- Bake ribs in the preheated oven for 1 hour.
- Stir ketchup, rice vinegar, 2 tablespoons hoisin sauce, soy sauce, and fish sauce together in a bowl until baste is smooth.
- Brush ribs all over with baste. Continue cooking in the oven, turning and basting ribs all over every 15 to 20 minutes, until ribs are tender and falling off the bone, about 3 1/2 hours.
