What could cause ice pops (popsicles) to go soft in the freezer? I’m having a strange issue with the storage of ice pops (popsicles/ice lollies) in the freezer. I recently bought a new freezer and still have the exact same issue which we can’t figure out.
Whenever we buy ice pops in our house, we put them straight into the freezer. We sometimes leave them in the box but usually remove them, which doesn’t seem to make a difference to their texture. However, even if they’re rock hard going in, they keep coming out soft, sometimes even melted. Every single time.
Here’s the weird part: everything else in the freezer is rock solid frozen! No other foods go soft regardless of how long they’ve been in there.
Also, as I mentioned, it happened in our old freezer and now our new one (which is 4* freezing). How much or how little we have in the freezer seems to make no difference. This only happens with ice pops (and ice cream cones) but no other food.
This might sound silly, but the only change in my freezer storage habits since we first noticed this problem is that we bought silicone ice trays with lids a few months ago; two of them which we stack on top of each other in the very edge. Part of me wonders if there’s some kind of chemical (since they’re cheap trays that are no longer sold by the seller they’re purchased from online) that could be affecting the ice pops, since they’re usually the only food near the ice trays. Though I do switch foods around to check freezing is consistent in all parts of the freezer, which it is. But the tray idea sounds like superstitious logic even to me.
Am I missing some kind of storage wisdom in regards to frozen sweet treats?
Your freezer is set at too high a temperature, probably just below the freezing point. Pure water freezes at 32°F/0°C so your meats and vegetables are freezing just fine, however adding sugar and/or salt to water reduces the freezing point. A 30% sugar solution freezes at around 28.5°F, salt water is about the same. The fact they are mushy means your freezer is almost, but not quite cold enough to freeze your popsicles.
Frozen desserts aside your freezer is far above the recommended temperature, the FDA and virtually every other guideline I see says that freezers should be set to 0°F, which is -18°C, not because of the freezing point but because that's the highest ideal temperature for food to last long-term.
