Leftover tomato paste: Many times a recipe will call for just a tablespoon or two of tomato paste. To refrigerate what's left often means it will get overlooked and eventually thrown out because it did not get used before it went bad. Next time you have some leftover tomato paste, try storing it like this instead: Spoon out the leftovers into a small zipper baggie, measuring by tablespoons full as you go. Close the baggie and flatten it out to about a 1/4-inch thickness. Put a label on the baggie indicating how many tablespoons of tomato paste are in it and also the date it was put into the freezer. When your recipe calls for one or two tablespoons, note how many (tablespoons) there are in the bag, imagine the tomato past divided into that many squares and break off an appropriate amount. Return the unused portion to the freezer.
Leftover tea?: Freeze any leftover tea in ice cube trays. Use these "tea cubes" to chill the next batch of iced tea you make. The tea will not get diluted from the melting ice.
