You can pressure can celery, and it’s a fantastic way to preserve this crunchy vegetable for soups, stews, and casseroles all year long.
The process is straightforward, but it does require a bit of know-how and the right equipment to keep your celery safe and delicious.
If you’ve ever wondered how long to pressure can celery, the answer is typically around 25 to 30 minutes for pint jars and 30 to 35 minutes for quart jars, depending on your altitude and the pressure required by your canner.
In this post, we’ll walk through exactly how long to pressure can celery, the steps to do it safely, and a few tips to keep your canned celery tasting great.
How Long Do You Pressure Can Celery?
When you pressure can celery, the processing time is crucial because celery is a low-acid vegetable.
Low-acid foods must be processed in a pressure canner to reach the high temperatures needed to destroy harmful bacteria like Clostridium botulinum.
So, how long do you pressure can celery exactly?
For pint jars, you’ll typically process them for 25 minutes at 11 pounds of pressure if you’re using a dial-gauge canner, or 10 pounds if you’re using a weighted-gauge canner.
For quart jars, the time increases to 30 minutes under the same pressure settings.
However, those times are for altitudes below 2,000 feet.
If you live at a higher altitude, you’ll need to adjust both the pressure and sometimes the time to ensure safety.
Always check your canner’s manual and the latest USDA guidelines because these recommendations can change.
It’s also important to note that pressure canning celery isn’t just about time; it’s about maintaining a steady, consistent pressure throughout the entire process.
If the pressure drops, you’ll need to restart the timer, which can affect the final texture of your celery.
So, whenever you pressure can celery, keep a close eye on your gauge and make sure your stove is providing an even heat source.
Why Pressure Can Celery Instead of Water Bath Canning?
You might be wondering why you can’t just use a water bath canner for celery like you would for pickles or jams.
The answer is simple: celery is a low-acid vegetable, and water bath canning only reaches 212°F (100°C), which isn’t hot enough to kill dangerous spores.
When you pressure can celery, the temperature inside the canner reaches 240°F (116°C) or higher, which is what makes it safe for long-term storage.
This is why every reputable source, including the National Center for Home Food Preservation, insists on pressure canning for celery and other low-acid veggies like green beans, carrots, and corn.
If you try to water bath can celery, you risk botulism, which is a serious and potentially fatal illness.
So, even though pressure canning takes a bit more time and attention, it’s the only safe method for celery.
Plus, pressure canning celery helps soften the fibers, making it perfect for tossing into soups without needing to cook it for hours later.
Step-by-Step Guide to Pressure Can Celery
Now that you know how long to pressure can celery, let’s go through the actual process so you can do it confidently.
The first step is to prepare your celery.
Wash the stalks thoroughly and cut them into pieces that fit your jars, usually about 1 to 2 inches long.
You can also chop them smaller if you prefer, but larger pieces hold up better during processing.
Next, pack the celery into clean, hot jars.
Leave about 1 inch of headspace at the top.
You can add a pinch of salt to each jar for flavor, but it’s optional.
Then, fill the jars with boiling water, making sure the celery is fully covered while still leaving that 1-inch headspace.
Wipe the rims, put on the lids and rings, and place the jars in your pressure canner.
Add the required amount of water to the canner according to your manufacturer’s instructions.
Seal the canner and turn on the heat.
Once steam starts flowing steadily from the vent, let it vent for 10 minutes to remove all the air.
Then, close the vent and bring the pressure up to the level needed for your altitude.
Start your timer once the pressure is steady.
Remember, for pints it’s 25 minutes and for quarts it’s 30 minutes at 11 pounds of pressure (dial gauge) or 10 pounds (weighted gauge) for altitudes under 2,000 feet.
When the time is up, turn off the heat and let the canner depressurize naturally.
Don’t rush this part.
Forcing the pressure down can cause liquid to leak out and may lead to seal failures.
Once the pressure reads zero, wait a few more minutes, then open the canner and remove the jars.
Let them cool undisturbed for 12 to 24 hours, then check the seals.
Tips for Perfectly Pressure Canned Celery
Pressure canning celery is pretty forgiving, but a few tips can make your results even better.
First, use fresh, crisp celery.
Older, limp stalks will turn mushy after processing.
Second, don’t overpack the jars.
Celery needs room for the water to circulate, and overcrowding can lead to uneven processing.
Third, always use up-to-date, tested recipes.
The USDA Complete Guide to Home Canning is a great free resource that gives exact times and pressures for your altitude.
Fourth, consider adding a little celery seed or a bay leaf to each jar for extra flavor.
And finally, store your canned celery in a cool, dark place.
Properly pressure canned celery will keep for at least a year, though for the best quality, try to use it within 12 to 18 months.
So, How Long Do You Pressure Can Celery?
You pressure can celery for 25 minutes for pints and 30 minutes for quarts at the appropriate pressure for your altitude.
It’s a safe, reliable way to preserve this versatile vegetable so you can enjoy it in soups, stews, and pot pies whenever you like.
Just remember to always use a pressure canner, follow tested guidelines, and adjust for your elevation.
With a little practice, you’ll be pressure canning celery like a pro and wondering why you didn’t start sooner.
