This is such a great idea! I love quick easy things like this. After freezing I would pop them in to a zip lock & pull out as needed
How often do you use a whole can of tomato paste? Me neither.
If you scoop the rest out onto wax paper in 1 tablespoon increments, you can freeze them and have them on hand for your next recipe. You don’t even have to defrost- it will cook down faster than you could find your can opener.
Hope it’s a beautiful Monday for you!
