- Sprinkle ribs with salt and pepper.
- Whisk together Kikkoman® Gluten-Free Poke Sauce and honey. Place rib racks in a large bowl, add sauce and combine until well coated.
- Cover bowl with plastic wrap and let ribs marinate for a minimum of 1 hour (up to overnight) refrigerated, turning occasionally to coat.
- Pre-heat oven to 325°F.
- Remove ribs from marinade and arrange, bone-side down, on a baking sheet, lined with a large sheet of foil (place ribs on one side of foil allowing space to fold foil over). Fold foil over ribs and seal edges tightly to form a packet around the ribs.
- While the ribs are in the oven, transfer marinade to a 2-qt. saucepan and bring to a boil. Reduce heat to medium-high and continue to simmer, stirring occasionally, until thick and syrupy, about 20 minutes. Set aside.
- Bake ribs for 2-1/2 hours. Remove from oven and let ribs rest at room temperature, still sealed in foil, for 1 hour. (Do not open; ribs will continue to cook and become tender.)
- Carefully open foil. Transfer rib rack to cutting board. Cut between bones to separate ribs.
- Baste ribs with reduced sauce until well coated and glazed. Transfer ribs to a serving platter and garnish with green onions and toasted sesame seeds.
