My changes to the recipe:
I added 4 cloves of garlic to the rub. I like a lot of garlic. But I didn't feel it was too garlic-y.
I was incredibly lazy when it came to making the glaze. I wanted the meat to be all brown and yummy so I covered the meat in the glaze and tossed it in the oven at 400º for 20 minutes. As you can see it got all yummy and caramelized.
I used a 6 quart crock pot but you could use a 4 quart if your loin was smaller. I used shoulder since that's what I had.
