Method
Rinse roast and pat dry.
Combine salt, pepper, garlic, and olive oil in a bowl. Mix thoroughly and apply to roast.
Smoke at 225 for three to four hours, shooting for an internal temperature of 130 degrees farenheit.
Tent under foil and let stand for thirty minutes, slice and serve with taters of your choice and maybe some mixed vegetables.
Notes
As this is a lean cut, I find it does better in a sous-vide. 16 hours at 133 would be perfect, with some butter in the bag for a lovely gravy after.
