I'm making stuffed cabbage and want to braise it in a sweet & sour liquid. I've made it in the past using tomato sauce, sugar and lemon juice, but I haven't been thrilled with it. I've heard of using sour salt instead of lemon juice, but I have no idea how to use sour salt in a recipe. I'm looking for a recipe with an eastern European flavor, kind of like my Bubbie might have made. Any thoughts or suggestions?
Also, for how long should it braise in the oven? Thanks!
