How to Can Tomatoes




Introduction: How to Can Tomatoes

About: I am a DIY enthusiast and first time mom living in Los Angeles who really just loves making and baking things for my family on a budget.

Easy step-by-step tutorial on how to can tomatoes.

Step 1:

Step 1 - Get tomatoes. small ones are much sweeter. 3 lbs = about 1 quart.

Step 2:

Step 2 - Slightly chop tomatoes. I used a processor.

Small tomatoes haver much more pulp than the larger ones for chunkier, less watery sauce.

Step 3:

Step 3 - In a very large sauce pot add tomatoes and 1/2 table spoon salt per pound of tomatoes. Cook the chopped tomatoes - the longer cooked the deeper the taste will get. About 1 hour or more to your liking.

Step 4:

Step 4 - In a smaller sauce pan chop then sauté three onions and 3 garlic bulbs in olive oil.

Step 5:

Step 5 - In the mean time sanitize the mason jars. You can use the dish washer.

The only canning tools are important is the jar grabber and the lid magnet.

Step 6:

Step 6 - Next step fill a larger pot with enough water to cover jars by 2 inches and boil.

Step 7:

Step 7 - Add some of the sautéed onions and garlic to the cooking tomato sauce. Not all only to your taste. Simmer on medium for a while - the longer the better.

Step 8:

Step 8 - Tip: The most important part of canning is the preservative especially if you are not going to refrigerate. I use lemon juice. At least two tablespoons per jar.

For spaghetti sauce I add the spices into each jar not into the sauce. This way you can make different sauces.

These are the ingredients.

Step 9:

Step 9 - After putting the lemon juice and spices into the jar you can now add the sauce. Add salt to the jar to taste.

Spoon any air bubbles from each jar.

I made three different sauces.

Spaghetti -added dried Italian seasonings and basil. You can also use fresh herbs. But dry works best for me.

Spaghetti w no salt - same as above but left out the salt.

Spicy spaghetti- Same as above add cayenne pepper, paprika, 5 dashes of Tabasco and 1 big squeeze of Sriracha. Careful add to your taste.

Step 10:

Step 10 - In a small pan boil the NEW jar lids. Never reuse lids. Boil for about a minute.

Step 11:

Step 11 - Wipe the top part of the jar must have a clean seal.

Carefully use the lid magnet to pick up the lids try to keep this part very sanitary.

Place the lids on the clean jars and screw in the top NOT to tightly just tight enough to hold the lid.

Step 12:

Step 12 - Carefully grab the filled jars with the grabber and gently place into the big flat bottom pot of boiling water. Make sure the jars have room and are not touching each other.

Boil for about 45 minutes. Read up on canning safety from different sources. USDA or the jar manufacturer for times and additives for different foods.

Step 13:

Step 13 - After the correct time turn off heat and remove the jars VERY carefully and let stand to cool.

Make sure you tighten the lids after they have cooled off a little.

Wipe off any residues and make sure to mark your jars accordingly.

Use the sauce for pastas pizzas or in any Italian recipe. Or keep it as a simple use the tomato sauce and add fresh chilies onion cilantro when your ready to make a dipping salsa for your party. I like habanero

Use your imagination.

    this is an excellent tutorial! my only concern is that the pot in which you're cooking the tomatoes appears to be a non-anodized aluminum one, and tomatoes are highly acidic. this can cause metal leaching to occur, and taint your finished product. always use stainless steel or enamelled iron surfaces for tomatoes, to avoid any unfortunate and unplanned additions to your otherwise delicious recipes! :)

    Thank you for the kind words about my tutorial. I think it might be the tone of the pictures but the pot is stainless steal. However your advice was very very helpful thank you so much :)

    You took a lot of good detailed pictures, very instructive. But it looks like your color balance is off. Your red is not showing up as red. You can probably fix this by editing the pictures with software to adjust the color and then just upload them to replace the ones you have.
