Here’s my Easy 3-Step Solution To Preserving Canned Tomato Paste:
You’ll need one small storage container to store the paste. I like the small Ball Plastic Freezer Jars
Use a can opener to open the top of the can of tomato paste. Remove the circular piece of metal top that comes off.
Flip the can over and do the same to the other side. Do not remove the metal; instead, push the tomato paste downward until all of the contents are in the storage container, then remove the metal top.
Close the lid on the container tightly and store freshly for a couple of weeks.
That’s it. No mess and no waste. Now you can use it to make Chicken Bouillabaise and numerous other recipes that call for small amounts of tomato paste, without worrying about needless waste.
