I was recently cooking gluten-free, and needed a substitute for soy sauce, which contains gluten. I was out of tamari, but recalled seeing a recipe for homemade soy sauce somewhere. A quick search came up with several versions of essentially the same thing – beef broth simmered with cider vinegar, molasses and spices that simulates soy sauce surprisingly well.
Once this mixture has cooked down, you can keep it bottled in the fridge for a few weeks; it also freezes well for longer storage.
