Handy kitchen tips
I buy a 500gm jar of tomato paste, and then spoon it into ice cube trays and then freeze. The following day, I pop them out into a freezer bag. I get about 22 cubes that are roughly of tablespoon measurement. Handy for casseroles and soups, and no more mouldy jars or waste.
Hope this is helpful to someone. Love to hear of any others :-)
