Grandma's BBQ Pork

I am so thankful that I had the good sense to ask my grandma for her bbq pork recipe a few years before she passed away! I still have her handwritten recipe that I cherish. Every Thanksgiving and Christmas that I ever spent with my dads side of the family included this delicious appetizer. I try to make it at least Thanksgiving or Christmas, if not both! I've got 4 pounds marinating in the fridge since last night (16 hours and counting!), but this recipe calls for 3 pounds and marinate overnight. I'm taking it to my brothers for Thanksgiving (an 8 hour drive!!) and I wanted extra meat and extra flavor. I tweak it a little bit..like add more of each ingredients...and mix the marinade in a small bowl first, but here is my grandma's recipe word for word:

Grandma Tillie's Barbequed Pork Tenderloin
