Universal Canning Method Recipe
Estimated Total Cooking Time
Total time varies by method; expect 1.5 to 4 hours, including preparation and processing.
Required Kitchen Equipment
Pressure canner or steam canner or large pot for water bath
Canning jars with lids and bands
Jar lifter
Funnel
Ladle
Bubble remover
Kitchen towels
Thermometer
Ingredients (per method example)
10 lbs (4.5 kg) of fresh tomatoes (or any desired vegetable or fruit)
1/4 cup (60ml) lemon juice or vinegar (for acidity, if required by recipe)
2 teaspoons (10g) salt (optional or to taste)
Instructions
Preparation: Wash and sterilize jars, lids, and bands. Prepare your vegetables or fruits by washing, peeling, and slicing them as needed.
Pressure Canning:
Place your pressure canner on the stove over medium heat. Add 2-3 inches (5-7.5 cm) of water.
Fill jars with prepared food, leaving a 1-inch (2.5 cm) headspace. Add acidity and salt if required.
Wipe the rims, place lids and bands, and using a jar lifter, place jars into the canner. Secure the canner lid.
Heat until steam flows from the vent. Attach the weight, allowing the pressure to build up.
Process jars at 10 psi for 25-30 minutes (adjust pressure for altitude as needed).
Turn off the heat, allow pressure to reduce naturally, then carefully remove the lid. Lift jars out to cool.
Steam Canning:
Preheat your steam canner with the required water level. Load prepared jars with 1/2-inch (1.25 cm) headspace.
Place jars in canner, covering the jars with the domed lid.
Maintain a steady steam, process for 45-60 minutes depending on the recipe.
Remove the lid at a tilt to prevent steam burn and use a jar lifter to remove and cool jars.
Water Bath Canning:
Fill a large pot with enough water to cover jars by at least 1 inch (2.5 cm). Heat to a simmer.
Add food to jars, maintaining a 1/4-inch (0.6 cm) headspace, and adjust lids.
Submerge jars in the boiling water bath, process for 35-85 minutes based on the recipe.
Turn off heat and let jars sit for 5 minutes before carefully removing them with a jar lifter.
Cooling and Storage: Allow jars to cool undisturbed for 12-24 hours. Test seals before labeling and storing in a cool, dark place.
Conclusion
Mastering the universal canning methods of Pressure Canning, Steam Canning, and Water Bath Canning transforms the home kitchen into a bastion of preservation.
