Minnesota Mix is a delicious, aromatic stewed tomato mixture including celery, onion and pepper.
Use it as a base for baked pasta dishes, casseroles, rice dishes, curries, soups and stews, etc.
Once you get used to the convenience of having it on hand, you won’t want to be without it. Make it at the end of summer when tomatoes are being sold cheaply in quantity. You can use paste tomatoes, or regular slicing type tomatoes, or a mixture of both.
Usually mixtures such as this require pressure canning, but this recipe was developed and tested by the University of Minnesota Extension service to be safe for water-bath canning. (It was also further tested by the National Center for Home Food Preservation.)
If you would like a product similar to this that was developed for pressure canning, see “Stewed Tomatoes and Vegetables” in the Ball / Bernardin Complete Guide (2015 edition), page 378 OR “Stewed Tomatoes” in So Easy To Preserve (2014 edition), page 59.
You may wish to double this recipe to get a full canner load of quarts / litre sized jars: if so, just do your calculations on paper first before proceeding so that you aren’t trying to do mental gymnastics in the thick of things.
Jar size choices: Either 1/2 litre (1 US pint) OR 1 litre (1 US quart)
Processing method: Water bath or steam canning
Yield: 6 x 1/2 litre (US pint) jars
Headspace: 2 cm (1/2 inch)
Processing time: Half-litres (pints) 40 minutes; litres (quarts) 50 minutes
Yield: 6 x ½ litres (US pints) or 3 litres (US quarts)
Serving size: 250 ml (8 oz)
Fat: 1.8 g
- 3 kg tomatoes (12 cups / 6½ lbs. Measured after after peeling and quartering. )
- 75 g green pepper coarsely diced (1/2 cup / 3 oz. Measured after prep. 1 medium-sized green pepper. )
- 75 g onion coarsely diced (1/2 cup / 3 oz. Measured after prep. 1 medium-sized onion.)
- 125 g celery coarsely diced (1 cup / 4 oz. Measured after prep. 1 large stalk. )
- Bottled lemon juice OR citric acid
- Peel and quarter the tomatoes.
- Wash, core, seed and chop the green pepper.
- Peel and chop the onion.
- Wash and chop the celery.
- Mix tomatoes, pepper, onion and celery together in large pot.
- Bring to a boil then lower to a simmer uncovered for 10 minutes.
- Meanwhile to each half-litre (pint jar) you will be using add either ¼ teaspoon citric acid or 1 tablespoon bottled lemon juice; OR if using litre (quart) jars, add either ½ teaspoon citric acid or 2 tablespoons bottled lemon juice.
- Pack tomato mixture hot into jars.
- Leave 2 cm (1/2 inch) headspace.
- Debubble, adjust headspace.
- Wipe jar rims.
- Put lids on.
- Process in a water bath or steam canner.
- Process ½ litre (US pint) jars for 40 minutes; process litre (US quart) jars for 50 minutes for altitudes up to 600 metres / 2000 feet. See table below.
The reason bottled (as opposed to fresh) lemon juice is called for is that it provides a guaranteed acidity level for safety.
Boiling water bath or steam canning
Tomato mixture is to go into jars piping hot. Steam-canning cannot be used as an option for litre / quart jars as the processing time would be over 45 minutes; 45 minutes is the safe cut-off time for steam canning lest the steam canners run out of water.
For processing times for altitudes over 600 metres / 2000 feet, you will need to contact the Minnesota Extension and ask them.
There are no tested pressure canning times, so you must water bath (or its equivalent, steam canning), or use one of the similar tested recipes noted at the top of this page.
|Jar size||0 to 600 m (1,001 - 2,000 ft)|
|1/2 litre (1 US pint)||40 mins|

An earlier version, as recent as 2006, apparently did not call for acidification as it does now. The guidelines were revised in 2014 by Suzanne Driessen, Extension Educator — Food Safety. It’s possibly then that the acidification was added.1
