How can I get the dried buttermilk starter completely mixed into the milk?
A. One of the easiest ways to incorporate the buttermilk culture into the milk is to secure a plastic lid on the container and shake until the starter and milk are fully mixed. If shaking isn’t an option, stir the starter into the milk as much as possible. The instructions allow for a bit of excess starter not to incorporate without damaging the final buttermilk.
