Boil water and wash tomatoes.
Put tomatoes into the pot, pour with boiling water and leave for 5 minutes. Now peel the tomatoes.
Then cut them into pieces, we need only flesh.
Put them into the pot and place it on medium heat.
Bring to the boil, the juice appears. We need about 15 minutes.
After boiling, pour out the juice.
Do the same two more times for 15 minutes, so the tomatoes are on heat for 30 minutes.
Now take the blender and make a puree.
Add salt, stevia, spices and bay leaves.
Continue cooking. It is important that puree boil but not burn. Slightly open the top so the liquid steam off. And stir from time to time.
Add vinegar.
Now boil the jar. I used 700 ml jar. Put the top into the boiling water. When the drops are large, the jar is ready. Put paste into the jar and close with a top. Tomato paste is ready. Have a nice meal.
