This recipe makes a high-quality, standard tomato sauce in the Italian style with the Italian holy trinity of carrot, onion and celery (the “soffrito”), with just a small bit of spicy zip.
Consequently, it’s very flexible in how you use it.
The recipe makes only three jars, so you may want to double or triple the batch. If so, just do your math on paper first before you start.

How to water bath process.
How to steam can.
When water-bath canning or steam canning, you must adjust the processing time for your altitude.
- Making fresh puréed tomato: You’ll need 4 kg (9 lbs of tomato. Wash them, and pass them through a food mill or strainer to remove the seeds, core, and peel. If you don’t have a food strainer or food mill, see here: Making tomato purée without a strainer or food mill.
- For the passata, 2 x 700 ish ml (24 oz) bottles will do.
- If using passata, stand emptied bottles upside down with caps on to drain well, then empty the bottles again into the pot. You’ll get an extra few tablespoons out of each bottle.
- You can use a food processor to chop the onion, celery, and carrot, even do them all at once if you weighed them out first after washing and peeling.
- Do not increase the onion, celery or carrot or it could throw the safe acidity balance off.
- Do not omit the lemon juice, it is what provides the safety (that and the processing of the jars.)
- For the garlic, you can use instead 1 teaspoon minced garlic from a bottle provided it is oil free. You don’t want to add oil to a home canning recipe unless it calls for it, as it could cause density issues during heat processing.
- The recipe doesn’t allow for litre (quart) jars.

- Added suggestions for starting with tomato passata;
- Increased initial first simmer time by 10 minutes to make sure carrot is tender (book says just 5 minutes.)
