    Does the recipe have to use vegetable broth powder? Can you use actual vegetable broth?

    • SkinnyMs  February 27, 2014

    What is Homemade Vegetable Broth Powder?

    • SkinnyMs  February 27, 2014

      Vegetable broth powder can be 1 teaspoon each of celery seed, dill weed, basil, oregano, and dried thyme. To that I add one tablespoon onion powder and 1 tablespoon dried parsley. Add 2 teaspoons of salt and mix.

    How much vegetable broth?

    • SkinnyMs  January 28, 2015

      If you would like to omit the vegetable powder and use broth instead you can replace some or all of the water for broth, so you can use 4 cups broth and 4 cups water or have all 8 cups be broth.
