Folks, I have found the best yogurt starter ever. It makes THICK creamy yogurt. I purchased at Walmart - a small tub of Stoneyfield Farm OIKOS oganic Greek vanilla or plain yogurt to use as a starter. A tablespoon or so added to a quart of milk does the trick!!! I did use pasteurized milk and added stevia instead of sugar and a dash of vanilla flavor. Try it - I hope you are as delighted as I am.
