It doesn't really go into a recipe. It's the same yellow mustard they serve as a topping in chinese restaurants or the little plastic packets that come with your take out chinese. You use it on egg rolls, rice, shrimp toast, etc. But usually it's not very potent. This stuff rocks.
maybe i am ordering wrong things but i have never seen it served with chinese food in DR. i will look for it next time i'm shopping in santiago.
btw, i have seen some recipes (like mac and cheese) call for mustard powder. could this be used?
