This recipe is from Lenard Rubin in the cookbook Savor the Southwest. This is an updated version of a classic Texas bbq. He likes to use this sauce during the last hour of bbq-ing beef short ribs, but it is equally delicious on chicken and pork. Have fun with it!
Place the mango, water and 1 tablespoon lemon juice in a blender and puree. Scrape into a saucepan and add the remaining ingredients. Bring the mixture to a boil over med-high heat; reduce the heat and simmer for 20 minutes.
Transfer the mixture back into the blender and puree until smooth. Pour back into the saucepan and bring to a boil over medium heat; simmer for another 20 minutes. Remove from the heat and cool.
