Raw goat milk, fermented into kefir is the main ingredient and what makes the dressing creamy. I use cultured butter and extra virgin olive oil for the rest of the fats in the dressing. I used to use avocado oil, ghee, and egg yolk, but I find that really high quality EVOO beats avocado oil innutrition and affordability. I switched from ghee to cultured butter for a little sweetness and creaminess. I omitted the egg yolk because people think that it might spoil and that they have to use it up really quickly. As far as the expiration goes, I have had this dressing in my fridge for over 3 months (with egg yolk) and it was perfectly preserved. You will note that I added a microscopic amount of green stevia powder, which is a real herb, to take the edge of the tartness of the kefir, but it needs to be a non-fermentable sugar so it will not continue to ferment and bust the jar. It seems that the kefir acts as a really great preservative to give it a longer life, under refrigeration of course.
