01 - Combine kosher salt, brown sugar, black pepper, smoked paprika, garlic powder, onion powder, pink curing salt, and ground coriander if using, in a mixing bowl and mix thoroughly.
02 - Rub the spice mixture evenly over all surfaces of the beef to ensure complete coverage.
03 - Place the cured beef into a large zip-top bag or non-reactive container, seal tightly, and refrigerate for 5 to 7 days, turning daily to redistribute the cure.
04 - After curing, remove the beef from the container, rinse thoroughly under cold water to remove excess cure, and pat dry with paper towels.
05 - Smoke the cured beef with hickory or applewood chips at 200°F for 2 to 3 hours, or until internal temperature reaches 150°F.
06 - Cool the smoked beef completely, then slice thinly against the grain for optimal texture.
07 - Pan-fry slices over medium heat in a skillet until they are crisp and golden brown on both sides, approximately 3 to 4 minutes per side.
