I was always cook sinigang at home using lemon as a souring agent ( pampaasim) because I cannot find any sinigang mix in my place. After a year, I finally got one from Walmart Paris, Texas. I love to shop there because the food is tax free and they sell some Asian food stuff . Last week was my lucky day. At last, they were selling Knorr Tamarind Soup Mix. I immediately cooked Chicken Sinigang for me and my children. I put in the freshly harvest eggplant from my garden. Too sad that I don't have okra and pepper anymore so I just settled for bell pepper for added flavor.
