Why? Because you can! And pickle, and jam, or otherwise celebrate the resurgence of the domestic arts our forebears held so dear. Put on your best apron and step into our kitchen, won't you?
The easiest way to make "passata': Canned tomato puree. It is a day long project, but you will enjoy this sauce for many months! It will bring some summer sunshine to the cold winter.
Sure, it's grueling, backbreaking, sweaty work, but one day's effort pays off with a year's worth of tomatoes!
If I can make only one tomato-y thing to remind me of summer all winter long, it would be this uncooked tomato sauce, frozen in batches. Perfection in its simplicity!
