You know how recipes call for one tablespoon of tomato paste? Yet, they are most often sold in these cans with more than one tablespoon!! Here’s a trick for saving the leftovers.
I spray an ice cube tray with non-stock spray. Spoon one tablespoon into each cube. Freeze. Pop out and into a freezer bag. They store well in the freezer and you just grab a cube when you need that one tablespoon.
The tubes of tomato paste are easier to use but more expensive. So, if your not springing for the tubes or they aren’t available in your store, this is a great trick!
