Step 1: Build a wood campfire with a good base of glowing embers. Feed fresh logs to the fire from time to time to generate plenty of wood smoke.
Step 2: Lightly brush the chops on both sides with olive oil. Season very generously on both sides with salt and pepper and crust on both sides with garlic and rosemary.
Step 3: Heat the shovel blade in the fire. This serves two purposes: It helps clean and sterilize the cooking surface and preheats the metal so it will sear the meat.
Step 4: Arrange the chops on the shovel blade, leaving an inch between each. Don’t overcrowd the shovel—it’s OK to work in several batches. Remember, in Australia grilling isn’t just about getting a meal to the table—it’s a whole evening’s entertainment. Thrust the shovel over the fire or lay it on the embers. Cook the chops until the internal temperature cooked to taste, 6 to 8 minutes per side for medium, turning with tongs. Let rest for 2 minutes before serving. Carpet the serving platter with the whole rosemary sprigs and lay the chops on top. Serve with lemon wedges for squeezing.
