When ready to cook, pre-heat the pellet grill to 180°F.
Remove the strips, and discard the leftover marinade. Dry the meat with paper towels, and dry coat with salt, pepper, and coriander.
Arrange the meat strips in a single layer on the smoker grill grates.
Smoke for about 3 hours, checking regularly after 2 hours, until the jerky is dry but still flexible. When the internal temperature has reached 180°F turn the smoker down to 145°F and smoke for as further 2 hours or the jerky reaches the texture you like.
