If you are following highly specific diets, like Keto, Whole30, or Paleo, it can be hard to find some ingredients. I have included a list of specific substitutions for you (also listed in the recipe box). Tapioca Flour - keto and whole30 substitute for flour Arrowroot Flour - keto and whole30 substitute for flour Sugar-free Chicken Broth - - Believe it or not, almost all chicken broths have cane sugar in them, but this one doesn't. It must be the natural goodness variety.
