To store extra: Even though tomato paste comes in tiny cans, we often just need a little bit for our dishes and have most of the can left over. The next time you need a small amount of your canned tomato paste, don’t throw it out. First, put the can in the freezer. When mostly frozen, remove both ends of the can. Use one of the lids to push out the paste. On a cutting board slice the rings into the desired amount and freeze the disks for use later. Brilliant!
Another option is to fill a few ice cube portions with your leftover paste and freeze for use at another time. When needed, the paste will pop right out for your next dish.
