Basting Sauce: Combine first four ingredients in a saucepan and mix well. Cook very slowly for 1 hour. Add sugar, butter, and root beer to mixture and slow boil for 30 minutes. Recommended for pork and game.
Wet Sauce: Mix all ingredients in a saucepan and simmer for 1 hour. Let sauce stand for 2 hours before serving on the side with barbecue.
Rub Dry Rub into both sides of skinned ribs. Place meat on grill away from coals, bone side down. Cook ribs 1-1/2 to 2 hours, never turning, before using basting sauce. Cook slowly for 3-1/2 to 4-1/2 hours, basting every 45 minutes to hour. Serve with Wet sauce on the side, or (not recommended by purists) baste with Wet sauce the last 1/2 hour.
NOTES: I have never cooked them for the 4 hours it calls for. I usually use the indirect grilling method on my gas grill and keep them on fairly low heat for an hour and a half.
