Soak newspaper in plenty of water. Wash herbs and shake dry. Clean and wash spring onions and cut into rings. Wash lemon hot, dry and cut into slices.
Wash the zander from the inside and outside and dab dry. Season inside with salt and pepper. Fill with herbs, spring onions and lemon slices. Spread a thin layer of baking paper with oil on one side. Place fish side by side on the oiled side.
Wrap first in baking paper, then in newspaper.
Slide the annealed charcoal in the grill tray to the right and left to create a charcoal-free zone in the middle of the grill. Place the fish there and grill indirectly for approx. 1 hour. After about 30 minutes, check that the newspaper is still moist enough to prevent it from burning.
Possibly put aluminium foil underneath.
