Freezing in Glass (No More Broken Jars!)

Creating can be accomplished by one of two different processes – the Blow and Blow, or the Press and Blow process.Once the parison is reheated to blowing temperature, air is injected to blow the container into shape. Press and blow methods are typically used for manufacturing wide-mouth bottles and as their size allows the plunger into the parison. Pressure canning the broth in glass jars in another option, like a , but requires more work and attention.Instead of using regular s and worrying about the shoulders, you can use wide mouth mason jars.Place your jars in a cardboard box (like the one mason sets are sold in) before putting in the freezer. They are pricier than canning or repurposed s, but might be an investment you’d like to make since you can also cook with them.
