To begin with Homemade Pizza Sauce, heat olive oil in a large saucepan and add crushed garlic followed by finely chopped onions, carrots and celery giving a minute in between each addition.
Saute them all together until the onions are translucent. At this stage, add the chopped tomatoes and allow the whole thing to cook until the tomatoes get soft.
Cover the pan with a lid while doing so as the tomatoes could splutter. Add tomato puree in between. This renders the sauce the ting of colour. Add some sugar to counter the acidic flavour.
When the tomatoes are relatively soft, the skin begins to peel, turn off the flame and add basil leaves along with the stalk and set it aside to cool.
Puree them all together, season with oregano, salt and pepper as needed in a mixer.
Store them away in an airtight container into the fridge. It remains fresh for a week.
