The ability to be creative and unconventional is a great asset as long as doing so falls within the bounds of religious norms and laws.
I use a storage container wide enough and tall enough to hold a plastic freezer bag. I place the bag inside the container.
Then I secure the bag to the container using the clamp.
This helps me be able to easily measure and pour homemade chicken stock into a bag for freezing without making a mess.
Remember to use this helpful hint, Color Dots in the Kitchen, to label the bag.
