Can square jars be used for freezing?

Our square jars are also great for storing in the freezer. Here are some tips for freezing:

   Cooling food before freezing has two important advantages:

   • Faster freezing: Chilling reduces the time it takes for food to reach the correct freezing temperature. This minimizes large ice crystals in the food, preserving the quality and texture of the food.
   • Food safety: Leaving food at room temperature for too long can cause bacteria to multiply and compromise food safety. Cooling before freezing reduces the risk of unwanted microorganism proliferation, ensuring food safety.
     
     
3. Allow to thaw: Allow the contents to thaw slowly to avoid even thawing and fogging of the glass.
   
   
4. Place the lid loosely on top: Place the lid loosely as the contents of the jar may expand when frozen.

How do I sterilize the square jars correctly?

To sterilize your jars and prepare them for the next use, we recommend the following procedure:
