Preparation of tomato sauce from tomatoes and tomato paste

Cut the peeled tomatoes finely and cook until the amount of liquid decreases by a third, stirring occasionally. By time – about 2.5 hours.
At this moment, we cook the onion with garlic.
Cut the onion into small cubes and fry in olive oil.
Garlic is also cut into small pieces and fried.
Add boiled tomatoes, sugar and salt to the tomato paste.
Then alternately lay the spices, paprika, oregano and finely chopped greens.
We put fried onions and garlic in the same place.
At the very end, add the wine vinegar and boil for about three more minutes.
We lay out the finished tomato sauce for the winter in clean jars and roll up the lids.
According to this recipe, about six liters of sauce are obtained from these ingredients.
