Peel the onion and the clove of garlic and cut into large pieces. Wash the rosemary. Pepper the Kassler neck on all sides, sprinkle with marjoram and place in a grill bowl. Put the rosemary on top. Distribute the onions and garlic evenly in the grill tray.
Cook the roast in the preheated grill at 180 ° C for approx. 45 - 60 minutes up to a core temperature of 65 ° C with the lid closed. Grilling indirectly does not mean placing the food directly over the embers. Then brush the roast with the honey and add the moist apple chips directly to the embers. Smoke for about 15-20 minutes. Let the roast rest briefly after cooking.
