Freezing soup?

My standard freezing food post

What you are attempting to do is a poor mans vacuum seal, air is the enemy. You'll need three things, you most likely already have all of them. Tupperware or these, these are what I use, they are cheap, re-usable and microwave safe. Also because they are cheap tossing them isn't an issue. So those, plastic/cling wrap like Saran wrap and aluminum foil.

Put the leftovers in your selected container, take a piece of plastic wrap and place it on top of the food. Push it down gently so it covers the food completely; really work it in against the food, your looking to remove the air. Make the piece of plastic wrap big enough the cover the edges of the container, hanging over the lip. Put the top on the container with the wrap hanging over. Once you put the top on you've got a pretty darn good seal that will protect the food. Next wrap that container in aluminum foil, again pressing it up against the container. Toss in the freezer, pull out and thaw/re-heat later.

Someone questioned the aluminum foil step, whether it was really required. Honestly I don't know, I've been doing this for a very long time and it works. If it ain't broke don't fix it! I have two shelves of different leftovers at the house that my son heats up after sport practice or weekends. It is not unheard of to pull out chili from 6 months earlier, good as new.
