In a small bowl, whisk together gochujang, red pepper flakes, soy sauce, Ty Ling Duck Sauce, rice vinegar, garlic, and Ty Ling Hot Oil. Set aside.
Bring a medium pot of water to a boil over high heat. Add in rice cakes and boil until softened and cooked through, about 3 to 5 minutes. Drain rice cakes in a colander and wash them with cold water until cool enough to handle. Thread rice cakes onto O-Yaki Skewers.
Turn on and heat up your grill to 350-400°F. While preheating, brush rice cakes with sauce all over. Place skewered rice cakes into your O-Yaki Skewer System.
Place O-Yaki Skewer System onto your lower-level grill grate. Grill until rice cakes develop light charing, around 5-8 minutes. Close the grill while cooking them. Transfer rice cakes to a platter and garnish with sesame seeds and chives. Serve immediately and enjoy!
