I left fresh strawberries, which I cleaned and froze, on the counter to thaw for 5 hrs by mistake. They mostly thawed. I want to know if I can refreeze them. I use them to blend them up in a meal replacement shake. They are less than a week old.
Refreeze them if you aren't using right away
Your strawberries started out well below freezing point of water. Home freezers operate at close to 0 F. Cooling is a function of temperature difference between substance and surroundings. Your strawberries are in no danger, unless they were absolutely covered in bacteria before freezing, like you had rubbed rotten halibut on them for some reason.
Any texture will be changed with freezing and blending, so don't worry about that.
I like frozen fruit in smoothies, as it gives thick texture without ice addition.
As far as I'm concerned if it was left out for more than 2 hours in room temperature you have the chance of it growing bacteria. You can freeze them again but to kill those bacteria you'll have to cook them which will make them taste terrible. If I was you, I would eat one or split it in the middle to see how bad they really are. Otherwise you can put them in the fridge and keep them there until you would like to use them.
