I rarely use an entire can of tomato paste in a recipe but hate to throw food away. So, I dallop a tablespoon at a time onto a piece of wax paper and then stick it in the freezer. Once it's frozen I place the tablespoons of paste into a plastic bag.
I like to keep the bag on the door of the freezer so I can easily find it. This morning I started a pot of beef stew and needed just a tablespoon of tomato paste. It peeled easily off the waxed paper and was so convenient. Better yet, I didn't have to open up a new can.
When they were filled, He said to His disciples, “Gather up the leftover fragments so that nothing will be lost.”John 6:12
