I buy the larger, more economical can of tomato paste and then measure it out by tablespoons onto a wax paper lined cookie sheet. Freeze until solid and then put the tablespoons of tomato paste into a ziploc bag in your freezer. You'll always have tomato paste for your recipe and it's pre-measured and ready to go!
