Haven't seen this here, that I remember anyway. Just thought about it this morn as I'm smoke'n a brisket. Take a potatoe and core it(like an apple) in the middle WIDTH ways, not length. (could do it length, i haven't tried that) After you core it, save that core and cut the core in about 1/3's, you will use each end as a plug. Put one plug in and put a little olive oil in the other side(the hole), sprinkle a little kosher salt in. Now take a clove of garlic(skin'd and nice) that would fit in there and shove it in there. Cap/plug the hole. put your potatoe on a some alum foil, pour a little olive oil on the tater, add a little salt and some of your favorite rub. Wrap in foil and stick it in the smoker. I like to take them off when they are kinda soft, not too soft, but you know. Tastes really good. Smoked garlic would be awsome!
