Every time we open a can of tomato paste, we use 1-2 tablespoons, put the rest in a container and put it in the fridge, with good intention to use it the next time we need tomato paste. 4 out of 5 times I go to use it, or find it buried in the back of the fridge weeks to months later, and of course it's moldy. 

I'd known about this little kitchen hack for a while, but always forgot about it. I finally started implementing it, and it's been so helpful in making us use the leftovers (instead of throwing them away or letting them go bad), and is saving money since we are fully using every little bit of food (yeah, I know tomato paste is like $.28 a can, but being less wasteful never hurt anyone).


So, here's what you do for this super complicated process:

  • Open a can of something and use whatever you need for your recipe. We freeze things like tomato paste, coconut milk (great to use in smoothies later!), pesto and broth. There are a lot of other things you can freeze, too, so just try it out!
  • Whatever is leftover, pour evenly into an ice cube tray and pop it into the freezer.
  • Once frozen, put the contents into a Ziplock bag for future use. 

This works well for baby food, too, since 1-2 cubes is a perfect serving size for an early eater. 

Now obviously, part of making this work is actually using the leftovers before they get turn all icy and get shoved into the deep, dark bowels of your freezer, so leave the Ziplock in a frequently used part of your freezer so you don't forget about it. 

Voila! A stupid easy money saving kitchen hack for those small amounts of food that would otherwise be thrown away or get moldy in your fridge. Let me know if you try it!
