Bring a large pot of water to a rolling boil (100°C / 212°F). Add the 15 eggs and boil for 8 minutes.
Remove the eggs and cool them immediately in cold water. Once cool enough to handle, tap and crack the shell all over to help the brine penetrate.
Prepare a container with a capacity of at least 1.5 liters.
Coarsely grind the allspice grains and bay leaves together with a small amount of salt. Place this mixture in the container along with the thyme, marjoram, mixed dried salad herbs, basil, and chives.
Bring 1 liter of water to a rolling boil (100°C / 212°F) with the remaining salt.
Place the cooled eggs on top of the herbs in the container. Pour the hot water over the eggs.
