1. Use only the best, top quality ingredients. Preserve fruits and vegetables at their peak of ripeness.

2. Process ALL home canned foods. (see Step-By-Step)
* High-Acid Foods in a Boiling-Water Canner
* Low-Acid Foods in a Steam-Pressure Canner

3. Follow only current, tested home canning recipes that
* include the appropriate processing method for the food type being canned;
* give a specific processing time for the food type and size home canning jar used;
* designate headspace;
* come from a reputable source offering up-to-date recipes, following acceptable canning guidelines.

4. Follow manufacturer’s directions for preparing home canning jars and two-piece vacuum caps. Complete instructions can be found on each Ball or Kerr package.

5. Fill hot jar with prepared recipe. Leave recommended headspace. Remove air bubbles by sliding a nonmetallic spatula between the jar and food; press gently on the food to release trapped air. Repeat around the circumference of the jar.

6. Wipe rim and threads with a clean, damp cloth. Center heated lid on jar. Screw band down evenly and firmly until a point of resistance is met – fingertip tight.

7. After processing, remove jars from canner; set jars upright on a towel to cool. Do NOT retighten bands or check for a seal while jars are hot.

8. After 24 hours, check lids for a seal. Sealed lids curve downward. Press the center of the lid to ensure it does not flex up or down. (Reprocess or refrigerate any unsealed jars.) Remove bands. Wipe jars and lids with a clean, damp cloth and dry. Wash bands in soapy water, dry and store.

9. Label and store jars in a cool, dry, dark place. For best quality, use home canned foods within one year.


Step-by-Step Canning

Using Boiling Water Canners

Most boiling water canners are made of aluminum or porcelain-covered steel. They have fitted lids and removable racks that are either perforated or shaped wire racks. The canner must be deep enough so that at least one inch of briskly boiling water will be over the tops of jars during processing. Some boiling water canners do not have completely flat bottoms. A flat bottom must be used on an electric range. Either a flat or ridged bottom may be used on a gas burner. To ensure uniform processing of all jars with an electric range, the canner should be no more than 4 inches wider in diameter than the element on which it is heated. (When centered on the burner or element, the canner should not be more than 2 inches wider on any side.)

Follow these steps for successful boiling water canning:
(Read through all the instructions before beginning.)

1. Before you start preparing your food, fill the canner half full with clean warm water for a canner load of pint jars. For other sizes and numbers of jars, you will need to adjust the amount of water so it will be 1 to 2 inches over the top of the filled jars.

2. Center the canner over the burner and preheat the water to 140°F. for raw packed foods and to 180°F. for hot-packed foods. You can begin preparing food for your jars while this water is preheating.

3. Load filled jars, fitted with lids, into the canner one at a time, using a jar lifter. When moving jars with a jar lifter, make sure the jar lifter is securely positioned below the neck of the jar (below the screw band of the lid). Keep the jar upright at all times. Tilting the jar could cause food to spill into the sealing area of the lid.

If you have a shaped wire rack that has handles to hold it on the canner sides, above the water in the canner, you can load jars onto the rack in the raised position and then use the handles to lower the rack with jars into the water.

4. Add more boiling water, if needed, so the water level is at least one inch above the jar tops. For process times over 30 minutes, the water level should be 2 inches above the jars.

5. Turn the heat setting to its highest position, cover the canner with its lid and heat until the water boils vigorously.

6. Set a timer (after the water is boiling) for the total minutes required for processing the food.

7. Keep the canner covered for the process time. The heat setting may be lowered as long as a gentle but complete boil is maintained for the entire process time.

8. Add more boiling water during the process, if needed, to keep the water level above the jar tops.

9. If the water stops boiling at any time during the process, turn the heat on its highest setting, bring the water back to a vigorous boil, and begin the timing of the process over, from the beginning (using the total original process time).

10. When the jars have been processed in boiling water for the recommended time, turn off the heat and remove the canner lid. Wait 5 minutes before removing jars.

11. Using a jar lifter, remove the jars one at a time, being careful not to tilt the jars. Carefully place them directly onto a towel or cake cooling rack, leaving at least one inch of space between the jars during cooling. Avoid placing the jars on a cold surface or in a cold draft.

12. Let the jars sit undisturbed while they cool, from 12 to 24 hours. Do not tighten ring bands on the lids or push down on the center of the flat metal lid until the jar is completely cooled.

13. Remove ring bands from sealed jars. Put any unsealed jars in the refrigerator and use first.

14. Wash jars and lids to remove all residues.

15. Label jars and store in a cool, dry place out of direct light.
