Ah, water bath canning – the perfect way to prolong the shelf life of your favorite fruits, vegetables, and jams! But if you’re new to this whole canning game, you might be feeling a bit overwhelmed.
Truth be told, there’s a lot of lingo floating around out there (and plenty of misconceptions!) about what water bath canning is, how to safely do it, and what goes into a safe batch of canned food.
But fear not. In this post, we’ll tell you everything you need to know about how to get started with water bath canning. Even if you’re a total beginner, this guide will give you the information you need to set out confidently on your canning journey.
Let’s get started!
What is Water Bath Canning?
Are you tired of throwing away perishable food items every year? Are you looking for a way to preserve your homegrown fruits and veggies? If the answer is yes, then you’re in luck. Water bath canning is the answer to all your food preservation questions.
Essentially, water bath canning is just a food preservation process that involves submerging jars filled with food and liquid in boiling water. This method is ideal for high-acid foods such as fruits, jams, jellies, and pickles.
The heat from the boiling water creates a vacuum seal around the lid of the jar, preventing bacteria and other spoilage organisms from entering. This vacuum seal also helps to preserve the color, flavor, and texture of the food for an extended period.
There are lots of benefits to getting started with this process, too. For one, it’s the most cost-effective way to preserve your fruits and vegetables. You can easily store your garden produce by canning, eliminating waste and saving money in the process.
Not only that, but properly processed canned food lasts for up to a year and provides a healthy, nutritious alternative to store-bought canned food.
Canning is also an excellent way to make gifts for friends and family. There are plenty of recipes out there for jams, jellies, and pickles – all of which make great gifts for the holidays or special occasions.
What Foods Should Be Water Bath Canned?
First and foremost, it’s important to note that water bath canning is best for high-acid foods. This means things like fruits (think: peaches, cherries, and berries), most pickles, and anything that has added acid (like salsa or tomato sauce).
On the other hand, low-acid foods – things like vegetables, meats, and some sauces – are better suited for pressure canning. Why? Because these foods are more susceptible to bacteria growth, and pressure canning ensures that the inside of the jars gets hot enough to kill off any potential problems.
But back to the good stuff. When it comes to water bath canning, here are a few foods that are perfect for the job:
- Jams and jellies: These fruity spreads are always a hit, and water bath canning makes them shelf-stable so you can enjoy them for months (if they last that long).
- Pickles: Whether you’re a fan of dill, bread-and-butter, or spicy pickles, you can water bath can them all! Just make sure to follow a trusted recipe and use the correct amount of vinegar and salt.
- Tomatoes: While most tomato products are better suited for pressure canning, you can water bath can whole or chopped tomatoes. Just make sure to add a little extra acid (like lemon juice) to keep them safe.
- Fruit: As we mentioned earlier, most fruits are great for water bath canning. You can preserve your favorite fruits in syrup, juice, or even just water. Perfect for snacking, desserts, or adding to smoothies.
- Relishes and chutneys: Many condiments, including relishes, chutneys, and other spreads, can also be processed in a water bath canner.
What Kind of Water Bath Canner to Buy
There’s nothing quite like the satisfaction of cracking open a jar of homemade jam or pickles in the dead of winter. But, before you can get to that point, you’re going to need a water bath canner.
Now, there are a few different options when it comes to water bath canners. You can go the traditional route and get yourself a large stockpot with a lid and a wire rack to keep your jars off the bottom. Or you can upgrade to a fancier electric canner with a built-in thermostat and timer.
Most beginners will do just fine with a basic stockpot or simple water bath canner. This is not only cheaper, but it gets the job done just fine, and it also allows for manual timing and temperature control (which is helpful when you’re still getting the hang of things).
If you repurpose a stockpot you already have to use as your water bath canner, the only thing to keep in mind is that you’ll want to make sure it’s tall enough to fully submerge your jars with at least an inch of water covering them.
Once you’re ready to up your canning game, an electric canner might be worth the investment. They’re easy to use and take the guesswork out of temperature control. Plus, they often come with handy features like a spigot for draining water and a removable rack for easy jar removal.
A Few More Tips to Consider
Before you dive in, here are a few tips to help you get started.
Start With Simple Recipes
As with any new hobby, it’s important to start with the basics before moving onto more complex projects. Find a simple recipe for something you already love, like strawberry jam or bread and butter pickles. Get the hang of the process before moving onto more intricate and involved recipes.
Always Use New Lids
This cannot be stressed enough. When it comes to canning, using new lids is non-negotiable. The sealing compound on the lids can only be used once, so make sure to always use new ones for each batch of jars. This will ensure that your jars seal properly and are safe for storage.
Follow the Directions Closely
Water bath canning isn’t the time to get creative or improvise. Follow the recipe directions closely, including processing times and measurements. Canning is a science, and messing with the ratios or processing times can result in dangerous and potentially deadly outcomes.
Use a Timer
Speaking of processing times, make sure to set a timer and stick to it. Over-processing can result in overcooked, mushy food, while under-processing can lead to bacteria growth and a whole host of health concerns.
A timer is a simple way to ensure that your jars are processed for the correct amount of time.
Be Careful Handling Hot Jars
Those jars are going to be hot, hot, hot, so take care when handling them. Use jar lifters and let the jars cool completely before moving them. Hot jars can easily shatter, causing injury and a big mess.
Label Everything
This may seem like a no-brainer, but it’s important to label your jars with the contents and processing date. You don’t want to accidentally open a jar of pickles thinking it’s jam, do you? Plus, having a label will make it easier to keep track of the shelf life of your preserves.
Make Sure You Sterilize
Before you fill your jars with delicious goodness, you need to make sure they’re clean and sterilized.
Wash your jars in hot, soapy water, rinse well, and then place them in a pot of boiling water for 10 minutes. Keep them in the hot water until you’re ready to use them. You can also use the sanitize cycle on your dishwasher, if you have one.
Be Mindful of How Tight You Screw the Rings On
While it may be tempting to tighten them as much as possible to prevent leaks, doing so can cause the lid to buckle, compromising the seal and leading to potential contamination. So, instead, follow the manufacturer’s instructions and only tighten the jar lids until they’re snug enough to stay put – no Hulk strength necessary.
Don’t Forget the Acid
When canning low-acid foods like tomatoes, make sure you follow the recipe to a T and add vinegar or lemon juice as needed to lower the pH level and prevent botulism.
Adjust for Altitude
If you live at a higher elevation, the boiling point of water is lower, which can affect the canning process. So, make sure to adjust your processing time accordingly to ensure your jars are heated for long enough to destroy any bacteria or microorganisms.
Know the Difference Between Raw Packing and Hot Packing
Raw packing involves filling the jars with raw food, while hot packing involves precooking or blanching the food before packing it into jars. Both methods have their pros and cons, so make sure to research your recipe to determine which is the best method for your needs.
Practice Makes Perfect
Don’t be discouraged if your first batch doesn’t turn out perfectly. Canning is a skill that takes practice, and each batch will get better and better. Keep at it, and pretty soon you’ll be a water bath canning pro!
Water Bath Canning 101: Instructions
Here’s a step-by-step guide to help you master this preservation process.
Step 1: Prep Your Equipment and Workspace
First things first, gather all of your canning equipment and set up your workspace. You’ll need a water bath canner, jars, lids, rings, a jar lifter, a funnel, a lid lifter, and a clean towel. It’s also smart to clean and sanitize all of your equipment and workspace before starting – this will save you time down the road.
Step 2: Choose Your Recipe and Ingredients
Now it’s time to choose what you’ll be canning! Whether it’s fresh produce, homemade pickles, or jams, make sure to use a tested recipe from a reputable source. Gather all of your ingredients and prepare them according to your recipe instructions.
Step 3: Preheat Your Canner and Jars
Fill your water bath canner about halfway with water and start heating it up. Place your jars in the canner, making sure they’re completely submerged in the water. Heat the water to a gentle simmer, keeping the jars in the canner to keep them hot and sterilized.
Step 4: Fill Your Jars
Using your funnel, carefully fill your hot jars with your prepared ingredients. Leave about ½ inch of headspace at the top of the jar to allow for expansion during processing. Remove any air bubbles using a clean knife or spatula.
Step 5: Place Your Lids and Rings
Wipe the rims of your jars with a clean towel and place your lids on top. Screw the rings on tightly, but not too tight – you want air to be able to escape during processing.
Step 6: Process Your Jars
Now it’s time to process your jars in the water bath canner. Place your jars in the canner using the jar lifter and make sure they’re completely submerged in the water. Cover the canner and bring the water to a rolling boil. The processing time will vary depending on what you’re canning, so always refer to your recipe for exact times.
Step 7: Remove and Cool Your Jars
After processing, use the jar lifter to carefully remove your jars from the canner and place them on a towel to cool. As the jars cool, you’ll hear a popping sound – this means that the lids have sealed properly. Let the jars cool completely before storing them in a cool, dark place.
How Many Jars Can a Water Bath Canner Hold?
The good news is that water bath canners come in different sizes, so you can choose the one that suits your needs.
Generally speaking, a standard water bath canner can hold up to seven quart jars or eight to nine pint jars, depending on the brand and model. But there are also larger canners that can hold up to 14 quart jars or 16 to 18 pint jars.
Now, before you go crazy with excitement and pack your canner to the brim with jars, you need to make sure to leave some space between the jars. The rule of thumb is to leave at least one inch of space between the top of the jars and the lid of the canner. This allows room for the water to circulate and create a vacuum seal, which is essential for safe and effective canning.
Where to Find Water Bath Canning Recipes
You can find all kinds of recipes online or in canning cookbooks, but make sure you’re paying attention to the validity of your sources. Always use tested and proven recipes.
Some great resources include the Ball Blue Book Guide to Preserving or the National Center for Home Food Preservation website. These sources provide a range of recipes for everything from jams and jellies to pickles and relishes.
While it might sound fun to get creative and try your hand at inventing your own recipe, we recommend you steer clear. You want to stay safe – and while there’s nothing wrong with getting creative in the kitchen, for canning, it’s best to stick with what’s already been proven to work best.
Grab your jars, get in the kitchen, and get cooking – it’s time to start canning!
