Recipe Notes

1) Soak cauliflower florets in a large bowl of cold water for at least 5 minutes or longer before using. This not only removes dirt and debris that might be stuck in it but also helps draw out any bitter flavors from it. Drain and shake off excess water before cooking. Soaking cauliflower is optional but I highly recommend it.2) If you are fond of garlic, feel free to add 3 cloves for extra flavor.3) Feel free to add as much or little broth to the soup until desired texture is achieved. Amount of broth may also vary a bit due to size of sweet potato and cauliflower being used.4) Slowly add apple cider vinegar to soup according to taste. Apple cider vinegar can also be substituted with lemon juice or sherry vinegar.
