Quality

Select only disease-free, preferably vine-ripened, firm fruit for canning. Do not can tomatoes from dead or frost-killed vines. Green tomatoes are more acidic than ripened fruit and can be canned safely with any of the following recommendations.

Recommended Varieties

Slicing varieties are good choices for making juice and crushed and whole tomato-products. Paste tomatoes are good for making sauce, ketchup, and purees. Yellow tomatoes are not really any lower in acid than red; they contain more natural sugars and therefore have a sweeter taste.

Freezing Procedure

Select firm, ripe tomatoes with deep red color. Wash and dip in boiling water for 30 seconds to remove skins. Core and peel. Freeze whole or in pieces. Pack into containers, leaving 1 inch of headspace. Seal and freeze. Use only for cooking or seasoning since tomatoes will not be solid when thawed. Note: Cooking or stewing tomatoes provides better texture and flavor.

Juice

Wash, sort, and trim firm, vine-ripened tomatoes. Cut in quarters or eighths. Simmer for 5 to 10 minutes. Press through a sieve. If desired, season with 1 teaspoon of salt to each quart of juice. Pour into containers, leaving headspace. Seal and freeze.

Stewed Tomatoes

Remove stem ends and peel and quarter ripe tomatoes. Cover and cook until tender (10–20 minutes). Place pan containing tomatoes in cold water to cool. Pack into containers, leaving headspace. Seal and freeze.

Canning Procedure

If this is your first time canning, it is recommended that you read "Let's Preserve: Basics of Home Canning." Wash jars. Prepare lids according to manufacturer's instructions. Fill hot tomato products in jars. Remove air bubbles. Wipe sealing edge of jars with a clean, damp paper towel. Add lids and tighten screw bands. Process in a boiling water canner, atmospheric steam canner, or pressure canner.

To Process in a Boiling Water Canner

Fill canner halfway with water and preheat to 180°F for hot packs or 140°F for raw packs. Load sealed jars onto the canner rack and lower with handles, or load one jar at a time with a jar lifter onto rack in canner. Add water, if needed, to 1 inch above jars and add canner cover. When water boils vigorously, lower heat to maintain a gentle boil and process jars for the time given in the recipe. After processing is complete, remove the canner from heat and remove the canner lid. Wait 5 minutes, carefully remove the jars from the canner with a jar lifter, and place them on a towel or rack to cool for 12 to 24 hours.

To Process in an Atmospheric Steam Canner

Preheat the base of a steam canner that has been filled with the amount of water designated in the instruction manual that comes with the canner (usually about 2 quarts). Set the rack in the base of the canner. Heat water in the base of the canner to 180°F. As each jar is filled, place it on canner rack, keeping the cover or lid on the atmospheric steam canner as you work. When all jars are in the canner, bring the canner to a boil over medium to medium-high heat until a steady column of steam at least 6 inches long escapes from the vent hole(s). Processing time begins when there is a steady column of steam 6 to 8 inches long. Slowly adjust the heat to maintain a steady column of steam throughout the processing time. After processing is complete, remove the canner from heat and remove the canner lid. Wait 5 minutes, carefully remove the jars from the canner with a jar lifter, and place them on a towel or rack to cool for 12 to 24 hours.

To Process in a Pressure Canner

Place jar rack, 2 inches of water, and sealed jars in canner. Fasten lid and heat canner on high setting. After steam exhausts for 10 minutes, add weighted gauge or close petcock to pressurize the canner. Start timing the recommended process when the desired pressure is reached. Regulate heat to maintain a uniform pressure and process the product for the time given in the recipe.

When processing is complete, remove canner from heat. Air-cool canner until it is fully depressurized. Slowly remove the weighted gauge or open petcock, wait 10 more minutes, and unfasten and carefully remove canner lid.  Remove jars from canner with a jar lifter and place on a towel or rack.  Do not retighten the screw bands. Air cool jars for 12 to 24 hours.  Remove screw bands and check lid seals.

Remove screw bands from the cooled jars and check lid seals. If the center of the lid is indented, wash, dry, label, and store jars in a clean, cool, dark place. If the lid is unsealed, examine and replace jar if defective, use new lids, and reprocess as before. Wash screw bands and store separately. Tomato products are best if eaten within one year and are safe as long as lids remain vacuum sealed.

To Process at High Altitudes

Process times in recipes are for altitudes at or below 1,000 feet above sea level. If you are processing in a boiling water bath at altitudes over 1,000 feet, follow process times in Table 2.

In a pressure canner, the processing time remains the same and the pressure is increased at higher altitudes.

In a dial gauge pressure canner:

  • At altitudes of 1,001–2,000 feet, process at 11 pounds pressure.
  • At altitudes of 2,001–4,000 feet, process at 12 pounds pressure.
  • At altitudes of 4,001–6,000 feet, process at 13 pounds pressure.
  • At altitudes of 6,001–8,000 feet, process at 14 pounds pressure.

In a weighted gauge pressure canner, the processing time remains the same at altitudes over 1,000 feet, but the food must be processed at 15 pounds pressure.

Acidification

To ensure safe acidity in whole, crushed, or juiced tomatoes, add 2 tablespoons of bottled lemon juice, 4 tablespoons of 5 percent vinegar, or ½ teaspoon of citric acid per quart of tomatoes. For pints, use 1 tablespoon of bottled lemon juice, 2 tablespoons of 5 percent vinegar, or ¼ teaspoon of citric acid. Add sugar to offset acidic taste, if desired.

Tomato Juice

Quantity.

See Table 1 for guidelines.

Procedure

Wash, remove stems, and trim off bruised or discolored portions. To prevent juice from separating, quickly cut about 1 pound of fruit into quarters and put directly into saucepan. Heat immediately to boiling while crushing. Continue to slowly add and crush freshly cut tomato quarters to the boiling mixture. Make sure the mixture boils constantly and vigorously while you add the remaining tomatoes. Simmer for 5 minutes after you add all pieces.

If you are not concerned about juice separation, simply slice or quarter tomatoes into a large saucepan. Crush, heat, and simmer for 5 minutes before juicing. Press both types of heated tomatoes  through a sieve or food mill to remove skins and seeds. Add bottled lemon juice, vinegar, or citric acid to jars (see acidification instructions above). Reheat juice to boiling. Add 1 teaspoon of salt per quart, if desired. Fill jars with hot tomato juice, leaving ½ inch of headspace. Adjust lids and process.
