Inspired by conversations on the Food52 Hotline, we're sharing tips and tricks that make navigating all of our kitchens easier and more fun.

Today: Virginia Willis, author of Southern Living Little Jars, Big Flavors, gives us a step-by-step guide to boiling-water canning.

Gingered Beet Pickles

Down South the age-old art of home canning is known as “puttin up” -- and oh, do we know how! I grew up in a family committed to preserving. Both of my grandparents had grown up in the country and both had lived during the Great Depression; they passed the practice along to their children. Preserving food was a way of life. 

Black eyed peas, butterbeans, and creamed corn were frozen; peaches, wild blackberries, scuppernongs, and muscadines were transformed into jams and jellies; green beans and tomatoes were canned in summer and in the fall the canning kettle held quart jars filled with peanuts, pears, and spicy chow chow. Cucumbers were sliced and transformed into bread and butter pickles, or quartered and packed with herbs and spices for tangy dill spears.

Canning was even taken on the road! My grandparents had a camper and traveled several times to Alaska from Georgia for months at a time. For the long trip they would pack cases of home-canned green beans. When they arrived in Alaska, they would fish for wild salmon. My grandmother, whom I called Meme, packed her trusty pressure canner -- and on the tiny stove of their motor home would put up salmon in the now-empty green beans jars. I was well into college before I had salmon that wasn’t home-canned. 

One technique that’s indispensable is boiling water canning. High acid foods are processed in the boiling water bath canner, ensuring the safety of the preserved produce by destroying harmful molds, yeasts, and some bacteria. Foods such as fruits, pickles, sauerkraut, jams, jellies, marmalades, and fruit butters are high acid with a pH level of 4.6 or lower can be preserved by boiling water canning. (Low acid foods require a pressure cooker and are a whole other story.) Boiling water canning consists of a large pot, tall enough to fully submerge the canning jars with an inch of water over top. The pot is used for both the sterilization of jars prior to filling and also for boiling the jars once they are filled. Follow these instructions so you can get busy with putting up!

Sterilize Jars & Prepare Lids

Sterilizing jars from Food52

Place your clean canning jars on a rack in the bottom of the canning pot, and add water to fill the jars and cover them by two inches. (If you don't have a canning rack, you can make one yourself by tying jar lids together in a circle with twine.) Cover the pot, and bring the water to a rolling boil over high heat. Add the lids to the hot water. After the water reaches a boil, boil them for 10 minutes, then reduce the heat and maintain at a simmer until you’re ready to fill the jars. Jars must be hot when food goes into them. 

Fill & Process Jars

Jars on baking sheet from Food52

Line a rimmed baking sheet with a clean towel. Remove jars from the simmering water using a jar lifter, and carefully pour the water in the jars back into the pot. Place the jars upright on the prepared baking sheet. 

Pack any recipe-specified solid ingredients (such as herbs or cut vegetables for a pickle) into the hot jars. Ladle or pour hot mixture or brine into the hot jars, using a widemouthed canning funnel to help keep the jar rims clean. Leave the recipe-specified amount of headspace, the space from the very top of the jar to the surface of the liquid or food inside. Repeat with remaining jars, working quickly to ensure that hot mixtures go into hot jars. 

Filling Jars from Food52

Tap the jars lightly to help the contents settle, and stir gently with a wooden utensil to free any trapped air bubbles. Add more hot mixture or brine as needed to reach the correct headspace. Wipe the rims clean of any spilled food using a clean kitchen towel dipped in hot water.

Use tongs or a magnetic lid wand to place a lid, white side down, on top of each jar. 

Wand from Food52

Place a band onto each jar; screw just until fingertip-tight. Carefully lower the filled jars into the pot of simmering water using the jar lifter to keep them upright.  Add more water, if needed, to bring the water level to two inches above the jar tops. Cover the pot, increase the heat, and return the water to a full rolling boil. After the water reaches a boil, set a timer, and boil for the amount of time specified in the recipe, adjusting if needed for your altitude.

Turn off the heat, uncover the pot, and wait until ?the boiling has subsided (about 5 minutes). Remove jars using the jar lifter, being careful to keep them upright. 

Transfer jars to a towel-lined or wooden surface where they can rest undisturbed 12 to 24 hours. Do not tighten or adjust bands. Lids may make a popping noise as the jars cool. Not to worry. That’s one sign of an airtight seal—and the sound of canning success.

Check Seals, Label, & Store

Bread and BUtter Pickles from FOod52

When the jars have cooled 12 to 24 hours, remove the bands and inspect the lids. Each lid should be sucked down a little in the middle and firmly attached at the edges. Press down on the center of each lid with your finger. If the lid doesn’t move, the jar is sealed and can be stored in a cool, dark place for up to 1 year (or as specified in the recipe).

If the lid center depresses and pops up again, the jar isn’t sealed and should be refrigerated immediately and its contents used within a few days.

Since I took a canning class about four years ago, I started canning everything! Most useful are probably the quarts of tomatoes I put up (I do about 40 pounds, and if I'm judicious, they'll last until it's tomato season again). Most fun are jams -- I love adding chiles, star anise, ginger root, lemongrass, black pepper, and whatever strikes my fancy to jam made with fruit from the market or begged, borrowed, and foraged. The best ever was a stonefruit-chile made with a combination of plums we'd found by the lake, others we'd harvested from my mom's tree, and a few very ripe peaches the neighbors couldn't use.

How do you use the Weck jars... I love the way they look -

I just did my first batch of fig preserves from my back yard tree. I may do some whole pickled figs too with the smaller ones.

yum. I love fig preserves with just a bit of lemon. You are so lucky to have a tree in your back yard!

I'm also eyeballing my neighbor's prickley pear cactus that drops fruit in my yard this time of year too.

The instructions above suggest that the lids should be boiled for ten minutes with the jars. The lids should not be boiled at all. They should be put in a separate pan of water that's been brought to a boil, but then turned off. (Boiling can affect the integrity of the rubber seal.)
Here is what the Ball Canning site has to say about this:

"Wash jars, lids and bands in hot soapy water. Rinse well. Dry bands; set aside. Jars and lids must be preheated and kept hot until they are used. To preheat jars and lids, completely submerge them in water that has been brought to a simmer (about 180°F). They should remain at this temperature until they are used, removing one at a time as needed. DO NOT boil lids. If jars are used for any recipe that is processed less than 10 minutes, the jar must be sterilized. To sterilize jars, submerge jars in water and boil 10 minutes. (For altitudes higher than 1,000 feet above seal level, refer to Canning Basics.) Allow sterilized jars to remain at a simmering temperature until they are used."
http://www.freshpreserving... (under the question about "special steps").

Note, too, that if the canned items are to be processed for 10 minutes or more, you don't need to sterilize the jars in boiling water for ten minutes. That's a big time saver!

Thanks so much for your input and advice! I wholeheartedly trust Ball. I guess it's a habit from my mom and grandmother, but it does make sense it might affect the rubber. I do love your point about sterilizing for 10 minutes isn't necessary if the jars will be processed for 10 minutes! Thanks so much for reading. Best VA

Another sanitization time saver is brewer's sanitizer, Star San. I wash all of my jars, rings and lids, equipment, spoons etc. in Star San solution before canning. I then boil the jars for five minutes, and process for ten minutes.

You're using your jar lifter upside down!

Oh my goodness. Busy day at the photo studio and a hand model that wasn't am experienced canner. Thanks so much. We've removed the incorrect photo. Thanks for reading!

I just made fig jam from homegrown figs. yum!
