G Sauce Serrano and Charcoal hot sauce is the concoction of Chef Gary Nguyen from Los Angeles, CA. Serrano peppers and active charcoal powder are key ingredients in this sauce. However, the fermenting with no sugar, only with the support of rice and sugar content from pineapple is what makes this product standout. This is different from the hot sauce you find at your local grocery store. A product with no preservatives, uniquely blended for your enjoyment. This will be your new favorite hot sauce.
