Cut the Tomatoes into an X Shape
Put them in a pan with 3 cups of water. Turn on the heat to high and let the tomatoes boil for 3 minutes
Remove all 6 tomatoes from the pan if they have boiled properly and peel the skin
Take 3 tomatoes and blend smoothly
Now put a pan on the stove and keep the heat medium-high. Put olive oil and give it 1 minute to be hot
Saute garlic and onion
This time, you need to chop the remaining 3 boiled tomatoes and remove the seeds.
Now, add the chopped tomato with sauteed onion and garlic and keep stirring to mix well
Saute them for 5 minutes
Now add sugar, basil, and tomato paste (you made with 3 boiled tomatoes) to the mixture. Stir to mix well
Cover the pan with its lid and simmer for 5 minutes
When the mixture gets thickened, add butter and tomato sauce. Keep stirring to mix them properly
Let the mixture even saute for 2 minutes at medium-low heat
Now your pizza sauce is ready
