Place tomatoes in the pot
First you need to core the tomatoes. Get rid of the cores and then cut the fruit into four pieces. Place these tomatoes into the Dutch oven or any other large pot.
Add water, onion, celery and parsley
Now add water, onion, celery and parsley into the large pot. Boil the mixture under medium-high heat settings. After this, reduce the heat to medium-low and gently heat the pot for almost half an hour. Remember to cover the pot when simmering the mixture.
Blend the mixture
After simmering the mixture, pour it into a blender or food processor. You need to mash the mixture with help of a hand blender or in a food mill. Later pour the mixture back into the Dutch oven or the large pot.
Add salt, paprika, parsley and sugar
Next you need to add salt, paprika, parsley and sugar into the tomato juice you made. Blend it after adding these ingredients. Remember to stir by hand in order to blend.
Now you need to cool the tomato juice you made. Pour the juice into a jar and then place it in a refrigerator. You need to serve the juice chilled. Instead of a jar, you can pour the juice into a pitcher.
