This definitely does not belong here but it is odd and doesn’t really belong anywhere else either: my grandson loves freezer pops the kind in the plastic tube that you freeze and eat. We discovered Snapple Sorbets. We ate them all summer long. Their taste was a little more adult favor, He and I fought over the mango flavored one.
The last box we bought had two sour apple tubes and one would not freeze. It is still in the freezer after 3 months and hasn’t formed a single ice crystal.
What could ca8se that? Is it safe to eat/drink? Were the others safe to eat—skip that it’s too late now. Would you buy the product again?
