I have not tried this recipe but it will give you an alternative method for cooking the pork. I don't know why you couldn't serve this in hamburger buns but the wraps are an interesting change from the usual.

Pulled Pork BBQ Wrap
Recipe courtesy Emeril Lagasse, 2000
Yield: 6 cups pulled pork

For Pork:
3 cups chicken stock
1 onion, coarsely chopped
2 carrots, coarsely chopped
2 ribs celery, coarsely chopped
1 tablespoon salt
1/4 cup liquid crab boil
1 pork butt roast, bone in (5 to 6 pounds)
1 tablespoon Creole seasoning, recipe follows
6 pieces Mountain bread or lavosh

In a large pot, bring chicken stock, onion, carrots, celery, salt and crab boil to a boil.
Season pork roast with Creole seasoning and add to boiling liquid and vegetables. Bring to a boil, reduce heat and simmer covered for 1 1/2 hours, or until fork-tender. Reserve cooking liquid and vegetables separately to use in BBQ sauce.

Preheat oven to 375 degrees F. Place roast on a rack and bake for 1 hour, or until meat pulls away easily with a fork.

Set aside to cool for 15 to 20 minutes, then pull meat away from the bone with a fork and pull into bite-size pieces. Coarsely chop meat if desired. Mix with 2 cups of the BBQ sauce before assembling sandwiches.

For BBQ Sauce:
2 cups reserved vegetables from pork
6 ounces reserved cooking liquid
2 teaspoons finely chopped garlic
2 teaspoons finely chopped ginger
2 cups ketchup
2 teaspoons cumin
1/2 cup brown sugar
2 teaspoons Worcestershire sauce
6 tablespoons cider vinegar
1 tablespoon Crystal Hot Sauce
Salt and pepper, to taste

In the bowl of a food processor, combine reserved vegetables, cooking liquid, garlic and ginger and process until smooth and the consistency of ketchup. Add remaining ingredients and process until thoroughly mixed. Season to taste with salt and pepper.
Toss pulled pork with 2 cups of the sauce before assembling sandwiches. Pass remaining sauce for dipping on the side.

Yield: about 4 cups sauce
