Combine all the ingredients in a medium size pot. Whisk well ensuring all the lumps are removed and everything is well blended. Simmer over low heat for about an hour or until the sauce has reduced by at least half and has turned lovely deep brown in color. Keep mixing to ensure the sauce does not burn or stick to the bottom of the pan.
Remove from heat and allow to cool before transferring to an air tight, sealed container. Makes about one cup of delicious gluten free BBQ sauce and can be stored in the fridge for up to a month.
