Step 1 - Selecting the tomatoes

It's fun to go pick your own and you can obviously get better quality tomatoes!  

At right is a picture of tomatoes from my garden - they are so much better than anything from the grocery store. You can use any variety, and they can be green, red or in between.

Also, you don't want mushy, bruised or rotten tomatoes!

Step 2 - Removing the tomato skins

Here's a trick you may not know: put the tomatoes, a few at a time in a large pot of boiling water for no more than 1 minute (30 - 45 seconds is usually enough)

then....

 Plunge them into a waiting bowl of ice water.

This makes the skins slide right off of the tomatoes!  If you leave the skins in, they become tough and chewy in the sauce, not very pleasant.

Step 3 -  Removing seeds and water

After you have peeled the skins off the tomatoes, cut the tomatoes in half.  Now we need to remove the seeds and excess water. 

Step 4 - Squeeze of the seeds and water

Just like it sounds: wash your hands then squeeze each tomato and use your finger or a spoon to scoop and shake out most of the seeds.  You don't need to get fanatical about it; removing just most will do. Another way to do it is to cut each tomato in half, across it, instead of lengthwise. Then just shake the seeds and juice out.

Step 5 - Drain and dice the tomatoes

Toss the squeezed (Squozen? :) tomatoes into a colander or drainer, while you work on others. This helps more of the water to drain off.  You may want to save the liquid: if you then pass it through a sieve, screen or cheesecloth, you have fresh tomato juice; great to drink cold or use in cooking!

Next chop them up - I like 1/2 inch size cubes. You will need about 3 quarts of  peeled, cored, chopped tomatoes

Step 6 - Get the jars and lids sanitizing

The dishwasher is fine for the jars; especially if it has a "sanitize" cycle.  I get that going while I'm preparing everything else, so it's done by the time I'm ready to fill the jars. 

Be sure to let it go through the rinse cycle to get rid of any soap!

 Lids:  Put the very hot (but not quite boiling; around 180 F, steaming water is fine)
water for at least several minutes. 

Note: everything gets sanitized in the water bath (step 7) anyway, so this just helps to ensure there is no spoilage later!)

Step 7. Mix or your own seasoning?

Either works equally well. The salsa mix for canning has the advantage of being tested and easy. It's basically corn starch, onion powder, salt and seasoning. It doesn't have any preservative to improve the canning, so the advantage is only that it is easier.  However, I like my custom-made from fresh seasonings better, so here is the recipe for that:

I use an electric chopper (food processor) to dice the seasonings fairly fine, about 1/8 inch cubes.

• 3 cups chopped onions
• 6 jalapeno peppers, seeded, finely chopped
• 4 cloves garlic, finely chopped
• 2 six-ounce cans tomato paste (adds body)
• 2 cups bottled lemon or lime juice (if you are using a mix, be sure to follow their recipe; the packet mixes often use vinegar instead of lemon juice)
• 1 tablespoon salt (optional)
• 1 tablespoon sugar (optional - you use Stevia (in a prepared form like Truvia, it measures same as sugar; if you use another form, you will need do your own conversion) - or Splenda, if you prefer, if you are on a sugar-restricted diet, or simply omit the sugar)
• 1 teaspoon black pepper
• 1 tablespoon ground cumin (optional)
• 2 tablespoons oregano leaves or chopped cilantro (optional)

Either works fine!

Step 8 - Mix ingredients in the pot and bring the sauce to a gentle simmer

<-- Start with the chopped tomatoes in the pot...

Add the seasonings and bring to a gentle simmer, just to get it hot (180 F, if you have a thermometer) there's no need to cook it; only to get it hot enough to ready it for water bath processing to kill any bacteria and enzymes.. Reduce heat and simmer for 30 minutes, stirring occasionally.

Taste it as it cooks. If you like the sauce hotter, add 1 teaspoon of chili powder.

Step 9 - Fill the jars with sauces and put the lid and rings on

Fill them to within 1/4-inch of the top, seat the lid and hand-tighten the ring around them.  

Be sure the contact surfaces (top of the jar and underside of the ring) are clean to get a good seal! 

Step 10 - Boil the jars in the canner

Put them in the canner and keep them covered with at least 1 to 2 inches of water. Keep the water boiling. Process the jars in a boiling-water bath for:

IMPORTANT:
The USDA says the only change you can safely make in this salsa recipe is to change the amount of spices and herbs. Do not alter the proportions of vegetables to acid and tomatoes because it might make the salsa unsafe. Do not substitute vinegar for the lemon juice.

I prefer a Pressure Canner or a taller water bath canner, shown at right - To order one, see the bottom of this page or Canning supplies!

Step 9 - Done

Lift the jars out of the water and let them cool without touching or bumping them in a draft-free place (usually takes overnight)  You can then remove the rings if you like, but if you leave them on, at least loosen them quite a bit, so they don't rust in place due to trapped moisture. Once the jars are cool, you can check that they are sealed verifying that the lid has been sucked down. Just press in the center, gently, with your finger. If it pops up and down (often making a popping sound), it is not sealed. If you put the jar in the refrigerator right away, you can still use it. Some people replace the lid and reprocess the jar, then that's a bit iffy. If you heat the contents back up, re-jar them (with a new lid) and the full time in the canner, it's usually ok.

Home Canning Kits

This is the same type of  standard canner that my grandmother used to make everything from applesauce to jams and jellies to tomato and spaghetti sauce. This complete kit includes everything you need and lasts for years: the canner, jar rack, Jar grabber tongs, lid lifting wand, a plastic funnel, labels, bubble freer, and the bible of canning, the Ball Blue Book. It's much cheaper than buying the items separately. You will never need anything else except jars & lids!
