BH - The grain structure of the loin varies from the shoulder in that it doesn't lend itself well to pulling..A loin can de very dry (no fat) even if slightly overdone. MAX DONE temp is 160º, and that is pushing it. Some go as low as 145º.. Remember, there is carry- over. So depending on the rest, thickness of the loin and covered or not, the final temp will be higher by a few degrees..A loin should rest 5 to 10 min..Maple syrup or brown sugar applied before the cook adds flavour. With no fat, the taste of a plain loin is bland (to me). Let us know how it turns out.
