The following steps Artikel the entire process, from preparing the jars to cooling them after canning. Following each step meticulously is essential for successful and safe pressure canning.

Prepare the Jars and Lids: Wash your canning jars, lids, and bands in hot, soapy water. Rinse thoroughly. Sterilize the jars. While not strictly necessary for pressure canning, sterilizing the jars helps ensure the longest possible shelf life, especially if the processing time is less than 10 minutes. Keep the jars hot until ready to fill.

Place the lids in a saucepan of simmering water (not boiling) to soften the sealing compound. Keep the bands at room temperature.
Fill the Jars: Pack the prepared celery into the hot jars, leaving the correct headspace.

Headspace is the unfilled space between the top of the food and the lid of the jar. It is crucial for creating a vacuum seal during processing.
Add Liquid (If Using): If your recipe calls for it, add the appropriate liquid (water, broth, etc.) to the jars, ensuring the celery is adequately covered. Remove air bubbles using a nonmetallic utensil, such as a plastic knife or chopstick. Gently insert the utensil around the inside of the jar to release trapped air.
Wipe the Jar Rims: Use a clean, damp cloth to wipe the jar rims thoroughly. This removes any food particles that could interfere with the lid’s seal.
Apply Lids and Bands: Center a lid on each jar. Screw on the band fingertip-tight. Do not overtighten, as this can prevent proper sealing.
Load the Pressure Canner: Place the filled jars on the rack inside the pressure canner. Follow your canner’s specific instructions for loading. Ensure there is enough water in the canner as specified in your canner’s manual.
Venting: Before pressurizing the canner, vent it to remove air. This is a crucial step for accurate pressure readings.

Most pressure canners require venting for 10 minutes. Follow your canner’s instructions for the specific venting time.
Pressurizing and Processing: Once vented, close the canner according to the manufacturer’s instructions. Bring the canner to the correct pressure for your altitude.

The processing pressure and time depend on your altitude. Use a reliable source, such as the National Center for Home Food Preservation (NCHFP) guidelines, to determine the correct pressure for your elevation and the recipe you are using. For example, at altitudes below 1,000 feet, you typically process at 10 pounds of pressure (psi). At higher altitudes, the pressure needs to be increased.
Maintain Pressure and Process: Maintain the correct pressure throughout the entire processing time. Fluctuations in pressure can affect the safety of your canned goods.
Cooling and Depressurizing: After the processing time is complete, turn off the heat. Allow the canner to cool naturally until the pressure gauge reads zero. Do not open the vent to speed up cooling. This can cause the jars to lose liquid.
Removing the Jars: Once the pressure gauge reads zero, carefully open the canner. Remove the jars, using a jar lifter, and place them on a towel-lined surface, away from drafts. Leave the jars undisturbed for 12-24 hours.
Checking the Seals: After 12-24 hours, check the seals. Press down on the center of each lid. If the lid doesn’t flex up and down, it’s sealed. Remove the bands and gently try to lift the jar by the lid. If the lid holds, the jar is sealed.
Storage: Properly sealed jars can be stored in a cool, dark place for up to a year. If a jar doesn’t seal, refrigerate the contents and use them within a few days.
