  • Hi Cindy,

    I believe the reason that these store bought already frozen blueberries work this way is because they are put into a flash freezer by the manufacturer which expands the blueberries rapidly causing micro tears in their skin (why there is purple water/juice in the bag when you let them thaw). By allowing them to thaw once, these micro tears open up. Which then acts the same as puncturing them when they are fresh.

  • We have experienced major failure with FD blueberries, they were sticky and did not dry very well at all. These failures were when we first received the Medium Harvest Right over 3 years ago. We later learned that blueberries need to be punctured prior to FD. Fresh berries stick to the berry roller we purchased, and was just a mess.
    Why do purchased frozen berries that are rinsed, thawed, and refrozen do not required to be punctured? How does this process allow the berries to fully freeze dry?
    OR, we should try again with the newer software with the candy cycle.
    I’m very curious!!
    Thank you
