Yesterday while at Whole Foods, I was searching the international foods isle and came upon some Sweet and Tangy sauce. I have always used the San-J Gluten Free Tamari Soy Sauce. It seems that now they have introduced an entire line of gluten free Asian stir-fry sauces. There were a lot of other manufacturers making them as well. I recommend cooking up some sweet and sour chicken tonight. Let me know how it goes.
The line includes: GF Thai Peanut Sauce, GF Szechuan Sauce, GF Teriyaki Sauce, GF Sweet and Tangy Sauce, and GF Asian BBQ Sauce.
