Heat the broth in a small saucepan over medium heat. Add the garlic and ginger and simmer for 3 minutes. Stir in the molasses, Date Syrup, tomato paste, and black pepper and bring just to a boil. Reduce the heat to low and simmer for 1 minute. Remove from the heat, and then stir in the miso mixture, blended lemon, and rice vinegar. Taste and adjust the seasonings, if needed.
Allow the sauce to cool before transferring to a jar or bottle with a tight-fitting lid or pouring the sauce into an ice cube tray and freezing into individual portions.
