Quick Answer
To safely hot pack your jars for canning, immerse them in boiling water for 10-15 minutes to sterilize, then fill the jars with hot food, leaving a 1-inch headspace, and process for the recommended time in a boiling water bath.
Preparing the Jars
To hot pack your jars, start by immersing them in a large pot or canner filled with boiling water for 10-15 minutes. This will sterilize the jars and create a vacuum seal. Use a rack or basket to keep the jars off the bottom of the pot, and make sure the water level is at least 1 inch above the top of the jars.
Filling the Jars
Once the jars are sterilized, fill them with hot food, leaving a 1-inch headspace. Use a clean utensil to remove any air bubbles, and run a non-metallic utensil, such as a plastic spatula, around the inside of the jar to ensure the food is packed tightly. Wipe the rim of the jar with a clean, damp cloth to remove any food particles or spills.
Processing the Jars
Place the filled jars into the boiling water bath, making sure they are covered by at least 1 inch of water. Process the jars for the recommended time, usually 10-30 minutes, depending on the type of food and altitude. Monitor the temperature of the water to ensure it remains at a rolling boil throughout the processing time. After processing, remove the jars from the water bath and let them cool on a wire rack.
