Freezer bags are temptingly convenient. A nice neat roll, all sizes and clean. But buying plastic bags just to use them once and then throw them away really doesn’t make sense, either from a frugal point of view or an environmental one.
I’m trying to reduce the amount of plastic we use and one thing I’ve found that I can totally do without is purpose made freezer bags. Here are alternative ideas that work just as well.
Re-use yoghurt pots
One litre sized yoghurt pots with lids are perfect for freezing small batches of cooked food, stocks, fruit purees and any other liquid or semi-liquid food. They are also good for freezing berries. Write on the lid with a permanent marker or use a sticky label to identify the contents – otherwise you’ll find yourself getting out stock when you want berries and vice versa.
Re-use other plastic containers
Think twice before recycling or throwing out any sturdy plastic container. Ice cream tubs, margarine tubs and any other similar food containers can be saved and re-used in the freezer. Check the recycling number on the plastic to make sure it doesn’t contain BPA. Numbers 1, 2, 4 and 5 are very unlikely to; numbers 3 and 7 may do. Containers can be re-used several times, but if they start looking scratched or otherwise damaged then it is time to recycle them. Plastic in contact with food should always be undamaged to avoid possible chemical contamination.
Re-use cereal bags
The inner bags of cereal packets are a prime example of useful bags that rarely if ever get re-used. Save them up and use them as freezer bags. Make sure you shake all the fine crumbs out of them, then use them for freezing dry goods, such as bread, cookie dough, breadcrumbs. They could also work well for freezing blanched vegetables, if you have an excess in the garden. The only problem with these is sealing them effectively. Try to push as much air out as possible, then fold over the ends of the bag at least twice. Close it with a peg or a tie, depending on what works best for you.
There are more and more glass containers with lids available these days that are freezer proof. Some are also microwave proof. Start investing in a few of these as and when you can afford them. Having a good stock of permanent containers cuts down on the amount of disposable containers you use. Some people use canning jars to freeze food in. Make sure you leave enough space for expansion as the food freezes, so that the glass isn’t cracked by the pressure.
As a general rule allow food frozen in glass to defrost thoroughly before heating, as a sudden temperature change can shatter it.
Just this small adjustment in thinking will save you money and save the environment from that much more plastic waste. I’m sure there are plenty more possibilities that I haven’t listed here – do you have any freezer container ideas to share?
