Guyana Mango sour is a delightful sauce made with green mango. It is balanced with lime, garlic and of course chili peppers. A side of pepper sauce or sour is not just a side; in fact it's the part of a meal that brings it all together. A good condiment can take a dish to another level; a more intense level of taste and flavor. The mango really is the star of the show, and it should be, since there aren't many ingredients in the mixture besides mango, garlic, salt, and hot pepper. The method itself is so simple; boil mango with all ingredients, mash or puree and enjoy.
