I’ve done it but haven’t used them yet…. Hope it’s ok to do ! X
I assume as long as you defrost in the fridge they'll be fine.
I freeze in ice cube trays and once frozen transfer into a thick zip lock type bag so I can use the ice cube trays again quickly! 👍
Some jars aren’t made to withstand very cold temperatures and may shatter on freezing. They can’t also be placed straight into the microwave (if you use one) to defrost or heat up. I have bought the baby kilner glass jars that can be frozen. Maybe get some of those or check for glass jars that can be frozen
Follow .. I was almost freezing in glass jars before to read this post 🫣
