Tips If you prefer more creamy mix ¼ cup of half & half milk or boil the full milk for about 5 minutes longer to reduce the milk in volume to give more creamy texture to the yogurt. I have tried using starters from many store bought yogurt including organic or Greek yogurt, and they don’t work. I think because store bought yogurt has many artificial additives. Store bought yogurt is more firm because of the pectin. Yogurt can be made using 1%, 2% or full milk and full milk yogurt will have more body to it. There are two ways to make yogurt creamier. 1) With 3 cups of milk use 1 cup of half & half milk OR 2) boil the full milk for about 5 minutes longer to reduce the milk in volume to give more creamy texture to the yogurt.
