|Some of the non-plastic ware we use.|
There have been too many news stories about chemicals leeching into food from heated plastic for me to still be comfortable with using those containers on a regular basis. And like anything with a coating, once it gets scratched or damaged, even MORE of the questionable chemicals can get into your food, which is why hot leftovers go into glassware.
Buying a set of glass containers can run you $15-20, easily and if you have kids taking their lunches to school, you definitely don't want those containers being tossed into the garbage by accident. Even the most responsible kids mess up and throw away things they shouldn't (retainers, anyone?). My youngest still uses the plastic for lunches, but she's bringing sandwiches and other "cold" items.
Mason jars work great for storing leftovers in the fridge. Old pickle jars are good for large soup quantities. If you freeze them, make sure there is plenty of headspace because cleaning out shards of glass and semi-frozen soup out of your freezer does not make for a good time.
When I buy food in plastic containers (which does happen), I try reusing those containers. Large peanut butter jars have housed cookies for people at Christmas. Smaller, tallish, plastic containers hold my paintbrushes, buttons, and other crafty items. Instead of buying brand new containers for loose rice, pastas, lentils, and legumes, I keep those in labeled reused plastic containers.
side note: This is called REUSING, not RECYCLING. Big pet peeve is people saying they "recycled" something like a spaghetti sauce jar into a button container. That is REUSING.
I know I've left out so many more re-uses of items and so many more options for inexpensive glass containers. Let me know yours in the comments, I'd love to know.
