2 packets Truvia, Stevia, Splenda or your favorite sugar substitute

3-4 ice cubes

1. Combine all shake ingredients in a blender and blend at high speed until smooth.  Stop blender and stir with a spoon to help blend everything. Blend again for a few seconds.

  1. To thicken xanthan gum. first dissolve 1/4 tsp in a tsp of oil. Add that mix to a 1/4 cup of water and let it thicken up and add it to the item you’re thickening little bits at a time, because it gets very thick. Salad dressing cans out like store bought consistency. Tip for working with xanthan gum from salted pepper channel just a hint I thought you’d like Nancy
