For the sake of the historical record, my descendants, my failing memory, instructional purposes, whatever, I am recording the method I use to can tomatoes. It may be different from the way you can tomatoes in some small way. But it works for me, and it may for you
This is my method for canning tomatoes somewhat whole. I quarter them so they fit in the jars more efficiently.
Materials:
- Mesh strainer over a medium bowl (x2)
- 4 qt. saucepan ¾ full of boiling water
- Stainless steel bowl
- Ice
- 1 qt. saucepan ½ full of boiling water
- Water bath canner ½ full of boiling water
- Can lifter
- Dish towels (2)
- Colander
- Lemon concentrate
- 1 Tablespoon measure
- Serrated tomato knife
- Paring knife
- Knife sharpener
- 1 qt. canning jars, sterilized in the dishwasher
- 2 part lids
- Paper towels
- Food mill (Mirro Foley 2-Quart Stainless Steel Food Mill
)
- 2# (or about 11) small, handball sized round Italian tomatoes/1 qt. jar
Method:
- Sterilize the 1 qt. jars in the dishwasher or a pot of boiling water. Place them upside down on a towel to dry.
- Remove the stems and rinse and score the bottom of 11 canning tomatoes.
- Drop the tomatoes into the 4 qt. saucepan of boiling water and cover.
- Fill the stainless steel bowl with a dozen ice cubes and cold water.
- Remove the tomatoes from the boiling water once the skin peels and submerge them in the ice water. Do not overcook the tomatoes.
- Remove the skin, quarter the tomato, remove its top, and place these in the first strainer over a bowl.
- Scrape out all the seeds and put them in the strainer with the discarded skin and core. Place the quartered and seeded tomato in the second strainer over a bowl.
- Repeat steps 6 and 7 until all the cooled tomatoes are processed.
- Put 2 T. of lemon concentrate in a 1 qt. jar. Place the quartered tomatoes in the jar, occasionally gently taping the bottom of the jar on a folded dish towel on the counter top to help the tomatoes settle into the jar. Continue until the jar is full.
- Top the jar with the liquid drained from the quartered tomatoes and their refuse, leaving ½ inch space to the top of the lids.
- Carefully wipe the top of the jar lid with a damp, clean paper towel.
- Drop the 2 part lid into the 1 qt. saucepan of boiling water for one minute. Carefully remove and place it on top the jar, screwing it down firmly.
- Repeat steps until all the jars are full.
- I only process five quart jars at once. I tried doing seven, but two knocked into each other as I lowered them into the water bath and those jars burst in the processing, making a huge mess and wasting two quarts of tomatoes (super sad).
- Cover the jars with water 1" above the surface of the quart jars.
- Bring the pot to a full boil then reduce the heat to medium heat and process the tomatoes for 35 minutes.
- Remove the jars from the canner and cool on the counter top listening for the "ping" of the 2 part top that says sealing was a success.
- Once completely cooled, check the tops of the jars to be sure that the seal is strong. The top of the jar should not “pop” up and down when you press on it.
- Mark the jars as to their contents and the date.
- Run the discarded tomato bits through the food mill. From five quarts of waste, I milled 1 pint of tomato puree that I will use in my spaghetti sauce that I can next.
- Take the refuse of the food mill, the seeds and skins, out to the chicken so that they might process them into eggs and some excellent compost ingredients.
