In a saucepan, combine the beef broth, cider vinegar, and molasses.

Add in the garlic, ginger, and salt. Mix well.

Let the entire mixture simmer on the stovetop over a medium-low heat for about 10 to 15 minutes or until the sauce begins to reduce. The best flavor is when you've let it reduce to about half of it's original volume.

Store the finished sauce in an air-tight container (I like to use a glass jar with a plastic lid) in the fridge until ready to use. You may need to shake slightly before use. For most recipes, you can use this as a 1:1 replacement for soy sauce.
