Great idea! Easy easy to store soups and sauces in the freezer for sure! Details from Lifehacker:
Soups, sauces, and purees that you want to freeze can take up a ton of space if you pour them into plastic containers before freezing. This suggestion, from Lynne Rossetto Kasper of NPR’s The Splendid Table, saves space in your freezer and uses a trick you may already know to do it: freezing your soups in heavy freezer bags.
This part you may already be familiar with: She suggests getting a cookie sheet, laying it out flat with a paper towel on it, and then pouring your soup, puree, or other liquid into a heavy-duty plastic freezer bag. Then lay the bag flat on its side, on top of the paper towel. Seal all but the last inch of the bag, and then force out any air bubbles that may be in the bag before sealing it shut. You should have a nice, flat bag of liquid, sealed at the end. Lay down another paper towel, and repeat with as many bags as necessary. Then pop the bags in the freezer on their side until they’re frozen through.
Here’s the clincher: when the bags are frozen through, stack them up like file folders instead of leaving them on their side. They take up the same amount of physical space, of course, but horizontal space in a freezer is usually at a higher premium than vertical space. Keeping them upright makes them easier to remove when you need one, and keeps them out of the way, up against the wall. Do you use freezer bags for soups and stocks, or are you sticking to plastic containers? How do you save space in the freezer? Let us know in the comments.
