Preheat the oven to 350 degrees F. Place the beef ribs in a large roasting pan and pat dry.
Then mix the Musselman's Apple Butter, seasoned soy, Sriracha, fish sauce, and garlic in a medium bowl. Brush half of the sauce over the ribs and save the rest for later. Cover tightly with foil and bake for 3 hours, until the meat easily pulls off the bone.
Preheat the grill to high heat. Allow the beef ribs to rest for 15 minutes, then cut them apart between the bones. Brush them with more sauce and grill the ribs for 5-10 minutes per side until and crust or "bark" forms on the outside. Sprinkle with green onions, and serve warm, with a side of kimchi.
