This recipe is great.
The mixed ingredients (the prepared ingredients before putting into the freezer) actually tasted like sour cream. I had to use a less than half a cup (roughly 1/4 to 3/8 of a cup) of coconut oil as I just ran out in preparing this.
I could add some honey or stevia to make this more like sweet cream butter!
I substituted used psyllium seed husk for the soy lecithin and in the place of the xanthan gum, I used 1 tbsp chia seed and 1 tsbp flax meal with 2 tbsp boiling water
