Can you freeze juice in mason jars?
Considering this, can you put mason jars in the freezer?
Yes, you can freeze in mason jars. First of all, if the jars do decide to have an earth shatteringly good time in your freezer, the breaks tend to be clean and kept intact by the frozen liquid.
In this regard, can you freeze juice in glass?
If you are going to freeze anything long-term in glass, make sure the glass is either tempered (the type used for canning jars) or specifically labeled for freezing. Since even freezer-safe glass can crack as food expands, always make sure to leave about 3/4 inch of space between the top of the food and the lid.
Blend and Freeze: Another make-ahead option is to blend a smoothie in the blender, then pour the smoothie into freezer-safe Mason jars, and freeze. This option requires a bit of planning and freezer space. The night before you plan to drink the smoothie, place a smoothie jar in the fridge and defrost overnight.
