How to Make Cultured Buttermilk

  1. In a large bowl or container, whisk together 1 cup of powdered milk and 1 cup of water until fully dissolved and smooth.
  2. Add 1/2 cup of fresh, high-quality buttermilk (ensure it's relatively recent to ensure the culture is still active).
  3. Gently stir to combine the powdered milk mixture and fresh buttermilk.
  4. Cover the container and let it sit at room temperature (ideally 70-75°F) for 12-18 hours, or overnight. The longer it sits, the tangier it will become.
  5. Once the mixture has thickened and noticeably soured (this will depend on temperature and the activity of the starter culture – usually 12-18 hrs), refrigerate immediately to stop the culturing process.
  6. Your homemade cultured buttermilk is ready to use! Store it in the refrigerator for up to 2 weeks.
