Cafe Rio-Barbacoa Pork

If heaven doesn't have a cafe rio..... well... i know how to make this now, so i still want to go to heaven..

• One 5-6 lb. pork roast ( mine was tooele county stock show bought, halla)
• 1 liter Dr. Peppa-(next time im gunna try Pepsi, since it runs threw my veins, just no diet soda, and of course no coke, cause it's nasty!)
• 1 cup brown sugar ( an overflowning cup, cause it deserves that goodness)
• 3/4 cup white sugar
• 1 clove of garlic, minced
• 7 oz. can of chipotle peppers in adobo sauce
• 6 oz. red taco sauce 
• 1 tsp ground/dry mustard
• 1 tsp cumin
• 1/4 tsp cayenne pepper

Since Cafe Rio is of the devil and only serves Tamales on Thursdays ( I learned this the hard way and got yelled at by grandma Cafe Rio, boy did she make me feel like a doof) I make a bunch to get me through the other 6 days, then put the rest on a CORN tortilla with onions and cilantro, because that IS what goodness is. the end.
