We sometimes enjoy Chinese take out. Not sure it's authentic but it's a quick fix for busy nights. So I'm always repulsed at the thick sweet bright red sauce that comes with sweet and sour chicken balls. (which is always chosen by DH). I wonder why sweet and SOUR when it's is only sickening sweet. So last night we succumbed to Chinese take out in a different area and with his usual order of chicken balls comes the typical bright red sauce, BUT it was thin and definitely sour as well as sweet. Being thin a lot less stuck onto the chicken. Very good! I'm wondering if anyone knows where to get this or has any other comments. It only now occurred to me to google if you can make your own!
