Making a good tomato sauce needs a lot of time of preparation and cooking, and even more, if you don’t take care, the kitchen will finish with tomato everywhere! But the flavor of a home-made tomato sauce is incomparable to the commercial one.
The ingredients can be very different in every country, even in every family: basilic, carrot, pepper, garlic, vinegar, etc. can be added if you prefer. This is the recipe that my mother showed me.
