Tie the moose roast with kitchen twine and season with kosher salt. Let the dry-brined moose roast sit at room temperature for 2 hours.
Preheat the pellet smoker to 275°F
While the smoker is preheating, heat a cast iron pan over high heat with olive oil. Sear the roast quickly on each side to create a golden brown crust.
Sprinkle moose roast with seasoning mixture.
Place the moose roast in the pellet smoker for about one hour, or until it reaches an internal temperature of 125°F
While the meat is smoking, make the cranberry-mint sauce by heating the cranberry sauce, mint, cardamom, salt, and pepper in a saucepan. Cook it on low heat while stirring occasionally, let it warm through then remove from heat.
Once the roast reaches 125°F, wrap it in foil and allow it to rest. The meat will continue rising in temperature in the foil wrap, when it reaches 135°F you can let it breathe.
Once the meat has rested for 10-15 minutes, slice against the grain and serve with the cranberry-mint sauce and your favorite sides.
