The idea of thawing frozen food and refreezing it to make the popsicles raises concern for me. It’s known that when doing this you lose quality and it also increases the risk of bacteria forming since the thawed food enters and stays in the temperature danger zone until it is refrozen. It’s the equivalent of thawing chicken on the countertop over a days time instead of in the fridge over the course of a couple days.
Not true , you can thaw frozen fish food ( say the cubes ) in a little bit of water enough to fill these trays and then re freeze them , within a few minutes they can be back in the freezer so the amount of bacteria that can enter at this time would be minimal ? i don't think anyone would leave frozen fish food on the counter all day and then re freeze it say 8-10 hours later ??
