Barbocoa Pork

2 1/2 lb boneless country style ribs
3/4 cups brown sugar
6 oz. salsa
6 oz. dark soda (I used Pepsi)

I combined all the ingredients, except the pork, in a pot and boiled for a couple minutes.
This is your marinade.

Pour marinade over pork

I usually put pork in crock pot and pour over marinade, so I would think you don't need to thaw this before you cook it in the crock pot.
5-7 hours on low. Once the pork is tender shred.

We put it over rice as a salad or roll it up on warm tortilla with melted cheese.
