In a small saucepan over medium heat, stir together all the ingredients.
Bring to a boil, stirring frequently, reduce heat to low and simmer 2-3 minutes, until sauce has thickened.
Allow BBQ Sauce to cool, then store in an airtight container in the fridge until ready to use.
For the Chicken Legs:
Preheat oven to 375F
Place the chicken legs in a large mixing bowl, sprinkle with the salt, and coat with 1/2 cup of the BBQ sauce, cover and marinate for 30 minutes in the fridge.
Place the chicken legs on a baking rack over a foil lined baking sheet, baste with extra BBQ sauce, if desired, and roast for 45 minutes.
