We use a decent amount of tomato paste here at Casa De TOR. It is a key ingredient in Spanish rice which is one of our favorites and also in chili and many soups or sauces. The problem is that while we need it we never need very much of it, most recipes we make use a tablespoon or two of the stuff. We get it in little 6 ounce cans but since it is an ingredient in large recipes we can never use a whole can of the stuff inside of its shelf life once opened and put into the fridge. They cost about 50 cents each but it has just been driving me nuts.
I hate wasting food to the point where I am willing to go to dis proportionate lengths to be able to use it before it goes bad or preserve it. Wifey got to looking online and read about how some folks freeze tomato paste. The preferred method is to put it into ice cube trays. I made Spanish rice the night before last and today I took what was left and put it into an ice cube tray in the freezer. Once thoroughly frozen I intend to take the tomato paste cubes out of the tray, wrap them in wax paper and put them into a plastic bag. We should be able to get 4-6 recipes out of one of those small cans. Next time we cook something with it I will post on how it works out.
