How to preserve tomato puree for long time
We usually store tomatoes in the fridge for 10-15 days. Let’s see how to store tomatoes for longer time. We can preserve tomatoes by freezing them.
Here I’ll show you 4 methods.
We need to clean them before freezing. To a bowl, add water and 1/2 cup vinegar. Remove the stems from the tomatoes and put them in vinegar water. Soak for 5 minutes, wash under running water and dry the tomatoes. Wipe the water off with a dry cloth. Separate smaller tomatoes and bigger ones.
Let’s store the smaller tomatoes as it is. Remove the white part of the tomatoes and cut a cross in the back. This will make the frozen tomatoes easier to use. Put these tomatoes in a zip-lock bag, seal it without any air bubbles and put it in the freezer for 5-6 hours.
To thaw, put the frozen tomatoes outside for 15-20 minutes. Freeze the rest of the tomatoes.
Cut tomatoes into pieces. Put the pieces in a plate and wrap it with plastic wrap. This will prevent frost from forming on the tomato pieces. Cover with a wrap or silver foil. Put it in the freezer for 5-6 hours. To thaw, put the frozen tomatoes in water for 10 minutes or microwave for 20 seconds. Put the rest of the tomatoes in a zip-lock bag, seal it without any air bubbles and put it in the freezer. These pieces could be peeled easily and used as we wish.
Cut the tomatoes into pieces and put them in a bowl. Add 1/4 cup water and boil it. Boil for 10 minutes and let it cool down. Grind it into a soft paste. Fill the paste into an ice tray. Cover with a wrap or silver foil. This will prevent frost from forming on the tomato pieces. Put it in the freezer for 5-6 hours. Put these tomato cubes into a plate, take a zip-lock bag and move the cubes into it. Freezer friendly boxes also could be used. Put the tomato cubes in a zip-lock bag, seal it without any air bubbles and put it in the freezer.
To thaw, put the frozen tomato paste outside for 15-20 minutes.
We could use these tomatoes for 3-4 months.
