Sprinkle the roast with Korn to Rock and gently rub it in. Marinate for at least 30 minutes (overnight is even better).
Cook on a closed grill, rotisserie, smoker, or in a Dutch oven until the internal temperature reaches about 73–76°C, occasionally basting with a little apple juice. Let the roast rest for a few minutes before serving.
Tip: Place some grilled vegetables, potatoes, or sauerkraut under the roast (for example, in the Dutch oven) and cook them together. The meat juices and seasonings will blend with the other ingredients, creating a simple yet incredibly tasty side dish with delicious roasted flavors.
