Welcome to canning season in this Baking Beauty’s kitchen. I don’t can much, but when those tomatoes turn red, I’ve got my work cut out for me. Besides making salsa, I also make this Canned Tomato Soup.
This recipe comes from my Mother-in-law, I have no idea how long she has made this soup, but when I started dating her son 16 years ago, I know she was making the soup then already. I always found the soup to be too warm though. Like, beads of sweat on your forehead warm. But, that must have been a year for strong onions, strong peppers, and a few more dashes of cayenne, because I don’t find it to be too spicy anymore.
Ever since going gluten-free, I’ve been sure to make enough of this tomato soup to fill my pantry shelves, sometimes even making enough for a few years (you never know when you will have a bad tomato crop, so better to plan ahead). This soup has become a staple in our house, and I hope your family will enjoy it as well. You are going to want to print it out, put it in a plastic sleeve to keep it free of splatters, and bring it out whenever the tomatoes start ripening.
- 1 1/2 ice cream pails (24 cups) tomatoes, cut into chunks (I prefer to use Roma tomatoes because they are less juicy than other tomatoes
- 2 cups chopped celery
- 4 cups onions, roughly chopped
- 2 large green peppers, chopped (about 2 cups)
- 1 small bunch of parsley, roughly chopped (about 3/4 - 1 cup chopped)
- 1-2 bay leaves
- 1/2 tsp whole cloves
- Put chopped tomato into a large stock pot. Mash them with a potato masher to extract some of the juice. Begin to heat the tomatoes on a low-medium temperature while you prepare the rest of the vegetables.
- Add the rest of the ingredients to the tomatoes, and bring the mixture up to a boil over medium - medium/high heat, stirring often, being careful not to burn.
- Once ingredients have come to a boil, reduce heat and allow the vegetables to slowly boil for another 2 hours, or until the vegetables are all very soft.
- Remove bay leaf (if you can find it, if not, don't worry about it). Use an immersion blender to puree the mixture until smooth. Note: If you do not have an immersion blender, you will have to wait for your soup to cool before using your regular blender. Hot liquids in a blender can be very dangerous.
- Carefully scoop some of the soup mixture into a Chinois or rotary food press fitted over a large bowl. Press the juice through the press, and discard the peel and seeds. Repeat until you have pressed/strained all the soup. Reserve 2 cups of the soup mixture. Return the rest of the soup to the stock pot
- In a medium bowl, whisk together: 1/4 cup cornstarch, 1/4 cup granulated sugar, 1/4 cup salt, and 1/2 tsp Cayenne pepper
- Add 1/2 cup melted butter or margarine, and the reserved soup.
- Slowly bring the strained soup back up to a gentle boil. Whisk in the cornstarch mixture, and continue to boil until the soup has thickened.
- While the soup mixture is reheating, place your canning jars in a large canner with enough water to cover them by at least 1-inch, and bring to a boil. Boil for at least 10 minutes. Also place your lids in a pan of simmering water, and simmer for 10 minutes. This ensures that the jars and lids are sterilized before adding the soup to them.
- Lift the sterilized jars from the boiling water bath and empty them. Half should be emptied into the sink, and half should be emptied back into the pot to keep the boiling water level up.
- Fill each jar with tomato soup, to within 1 cm of the rim. Wipe the rim clean with a paper towel dipped in boiling water, and place the lids and rings on top of the jar. Return the jars to the boiling water bath and boil them for 20 minutes, well covered in water.
- Remove from waterbath and set jars on a dry towel, free from drafts. Allow to cool completely before checking that each jar has sealed (the lid is pulled down slightly, and no longer "pops" when you push on it). Label and store in cool, dark place. It is best to used home canned goods within 12 months.
- When pressure canner is full, adjust water to level as directed by canner manufacturer. Lock canner lid in place and follow manufacturer’s heating instructions. Vent canner–allow steam to escape steadily–for 10 minutes; close vent.
- When canner reaches the pressure appropriate for your altitude* and type of pressure canner, begin counting processing time. Process – heat filled jars – in pressure canner – 500 ml jars – 20 minutes at 10 lb (69 kPa). NOTE: processing times indicated are for a weighted gauge pressure canner used at altitudes up to 1,000 ft (305 m). When using a dial gauge pressure canner or canning at higher elevations, adjust pressure according to chart.
- When processing time is complete turn off heat. Allow canner to stand undisturbed until pressure drops to zero. Wait 2 minutes, and then remove cover, tilting it away from your face. Remove jars without tilting. Cool upright, undisturbed 24 hours; DO NOT RETIGHTEN screw bands. After cooling check jar seals. Sealed lids curve downward. Remove screw bands; wipe and dry bands and jars. Store screw bands separately or replace loosely on jars, as desired. Label and store in a cool, dark place.
