I saw this in the paper. Looked good so we tried it. Haven't had pork Loin in ages.
-The Coating Mixture:
-2 T hoisin sauce.
-2 T ketchup.
-2 T soy sauce.
-1 t hot Asian chili sauce.
-1 1/2 t grated fresh ginger
-2 cloves garlic, finely chopped.
Combine all ingredients and spread over pork.
Smoked @ 220º for an hour, then 400º for ~ 20 min. until done @ just under 160º. Rest ~ 10 min, slice and serve..A different and enjoyable taste with lots of juice.
Note: I folded the thin end over itself so the loin had an even thickness for done temperature uniformity.
