So I want to freeze some soup I made into portions. I prefer glass to all else but have had too many explode on me to try freezing jars. I have silicone measuring cups and was thinking I would use the cup one as like a mold and then pop them into a freezer bag? Think it's ok for me to freeze the measuring cups? And other preservation ideas? <img alt="" class="inlineimg" src="/img/vbsmilies/smilies/eat.gif" style="border:0px solid;" title="Eat"> Thanks!
