Keep in mind you want to freeze usable amounts in each bag. Don't try to put all the sauce together, then you have to defrost it all at one time. I'd do a bunch of 2 cup bag fulls, or however much sauce you think you'd use in a week.
they have really nice glasses with tops at no. 165 in maplewood village, you can put stuff in there, put the plastic tops on, and freeze them - and then they're not touching plastic, but glass (better for you!).
If you are using the plastic containers you should first spray them with Pam so that the sauce doesn't stain the plastic...have been doing that for years and I'm stain free!
it's a great tip, stain-wise, but it is the opposite of what you're told to do with plastics, they're not supposed to be used to store fatty foods (oil is pure fat), nor change temperature as with heat or freezing.
I've never tried it, but I've heard of people freezing sauces in ice cube trays, then pop them out of the trays into a larger container/bag to store in the freezer. Then you can easily grab and thaw the amount you need.
I'm familiar with Corning...both the product and the area! I think when you freeze in thinner glass the water freezing can expand and maybe break the glass. Corning is quite thick. But, no worries...my freezer, full of homemade meals in the basement, has kicked the bucket. And the ice maker in my regular fridge is kaput. Gotta love sub-zero~
I've done what grahamb suggest with some kinds of food - never sauce though. i.e. put it in ice cube trays, once frozen pop it out and put into ziplocs (probably safer as less surface touches the plastic). I've also taken some things (like applesauce) and spread them out on a cookie sheet and frozen it in sheets. Once frozen, pop out and break into pieces and store in ziplocs. That works, too. I've never done either of these tricks with sauce but I bet it would work fine. With sauce, I just spoon enough for one family dinner into a ziploc and freeze flat.
The problem I've found with freezing flat in ziplocs is that they all stick together and getting them apart is a pain. I've started putting sheets of paper between each bag (usually brown grocery bags cut up) and that helps. Another problem is that a teeny tiny pinhole in a bag can be a major PITA. (I guess only an issue if you re-use the bags, which I do.)
my condolences to your freezer, starsong! did you have any cool glass-related experiences being in corning? a woman i worked with gave me a righteous pair of earrings from the corning museum of glass.
i'm not just talking about corning-ware - corning is where the whole temperate glass (i.e. pyrex) was invented. there is so much glass that can be put in the freezer. i would not put a depression glass plate in the freezer - but pyrex glasses? yes. plastic is great for medical purposes, but when it comes to food, it should be used pretty sparingly (i.e. i use the plastic caps on the glasses that don't actually touch the food).
I have been freezing things in plastic for years and years and have never had a problem. I try to buy the freezer quality plastic. The thinner plastic containers crack very easily especially when dropped!
pthalates...bisphenol a.......alot of these plastics are xenestrogens...act like estradiol estrogen...i think most of us were under the assumption that the FDA was monitoring all of these things we use....(try searching for a lotion or makeup without parabens)...all found in breast cancer tissues........i think it is the heating of these things that creates the leaching...i guess i need to get back on the subject....sorry to drift....i know how MOLers hate when you dont stay on the subject at hand
