Cut your tomatoes so that they fit in your blender. Don’t overfill, otherwise they won’t blend properly.
Once fully blended, pour into your beverage dispenser jar.
Place in the fridge overnight.
In the morning, the pureed tomatoes will have settled on the top, with a thick layer of liquid on the bottom
Sit the beverage dispenser on the edge of your sink, open the spigot, and drain off all the excess liquid.
Then open the top of the jar and ladle out the tomato puree into freezer bags.
Be careful not to overfill, and make sure to place them on a flat surface, even in the freezer (you can use a cookie sheet if you need a more even surface)
Once frozen, you can transfer them to any spot in your freezer.
