Wondering how to freeze juice in mason jars?
Many people believe it’s not possible and instead transfer the item to a different container or baggy.
However, it is possible to freeze juice in mason jars. In fact, you can freeze most liquids successfully in mason jars and in this post I’ll show you exactly how I’ve been doing it for a number of years.
Tools & Equipment For Freezing Food
These are my tried and tested tools and equipment for freezing food.
Whether it’s fresh fruits or completely prepared meals these tools will make the process easier, and the food last longer and taste better!
Containers – We opt for glass containers as they are better for the environment, much higher quality and don’t stain like plastic, however they are an investment.
So if you’re short on money buy high-quality plastic containers in the meantime.
Just be sure that you buy your containers in a range of sizes as you’ll be using them to freeze and store a range of different foods.
Ziplock Bags – Invest in quality freezer bags and they’ll help keep out air, prevent frost and keep your food fresh for longer.
The majority of the high-quality ziplock bags come with a small area for you to write information about the food (i.e. what it is, when it was frozen and defrosting instructions) on the bag.
Ice Cube Trays – Ice cube trays can help you freeze more than just water. Instead, we use them for freezing small portions of food such as egg whites, tomato sauce, pesto etc.
Simply add the food to the tray, freeze and once frozen pop the food out and into a ziplock bag, then you can simply take one or two portions of food out and defrost as needed.
Foil Baking Containers – We use foil baking containers when we’re batch cooking frozen meals.
They are affordable, durable and come in a variety of sizes allowing you to portion out or put everything in one large container to be cooked at a later date.
If all that wasn’t enough, the majority of meals are safe to be cooked in the oven with the foil container. This reduces the amount of hassle, time and washing up you’ll have to do – winner!
How To Freeze Juice In Mason Jars
Glass is completely safe in the freezer, provided it’s tempered and you follow the instructions.
Sadly, the majority of these glass jars and containers don’t come with instructions on how to use them in the freezer.
However, if you look at your container you’ll probably notice a line somewhere near the rim of the jar.
On Ball and Kerr mason jars specifically, this is a thin line just under the rim of the jar.
Simply take your juice and pour it into the mason jar up to this line.
If you go above the line then you’ll risk the jar cracking and breaking as the contents inside expand in the freezer (and especially as the contract again when defrosting)
Simply put this line allows for enough space for the liquids inside the jar to play to science during the freezing and defrosting process.
Once your juice is in the jar and the jar has been filled to the line simply seal the container shut as normal.
If you can’t find a line on your container then I recommend allowing at least one inch of space from the bottom of the rim of the masonry jar just to be safe.
Be sure to write the contents on the container as well as the date it was frozen – it’s so easy to forget what an item is or when it was frozen when it’s been in the freezer for a couple of weeks (or months)
Juice is suitable for freezing for up to one year.
How To Defrost Juice In Mason Jars
It’s very important that you don’t subject your mason jar to thermal shock when defrosting your juice.
For this reason when defrosting be sure to remove the juice from the freezer and into the refrigerator to defrost naturally overnight (or for around 12 hours)
Alternatively, leave the mason jar out on the countertops for around four hours again to naturally defrost over a period of time.
In both cases be sure to put a towel or a dish under the mason jar to catch any liquid during the defrosting process and prevent it from going over your counter or your fridge in the process.
