Canning, the art of preserving food in sealed jars, is a time-honored tradition experiencing a resurgence in popularity. It allows you to enjoy the bounty of your garden or local farmers market year-round, reducing food waste and providing delicious, homemade meals. But before you dive headfirst into preserving peaches or pickling cucumbers, it’s essential to gather the right equipment. This comprehensive guide will walk you through everything you need to start canning safely and successfully.
Essential Canning Equipment: The Core Tools
The cornerstone of any canning operation lies in having the right essential equipment. These tools are not optional; they are necessary for ensuring the safety and quality of your preserved goods.
The Canning Pot: Your Boiling Water Bath or Pressure Canner
The canning pot is perhaps the most crucial piece of equipment. There are two main types: boiling water bath canners and pressure canners. The choice depends on the acidity of the food you’re canning.
Boiling water bath canners are used for high-acid foods like fruits, jams, jellies, pickles, and tomatoes (with added acid). These canners are typically large, deep pots with a rack inside to keep the jars from directly touching the bottom of the pot. Any large stockpot can be used as a boiling water bath canner, provided it is tall enough for the jars to be completely covered by 1-2 inches of water, has a flat bottom, and can safely handle the weight of the water and jars.
Pressure canners, on the other hand, are essential for low-acid foods like vegetables, meats, poultry, and seafood. These foods require higher temperatures than boiling water can provide to kill harmful bacteria, specifically Clostridium botulinum, which causes botulism. A pressure canner is a heavy-duty pot with a locking lid and a pressure gauge or weighted gauge to monitor the internal pressure and temperature. It is vitally important to follow the manufacturer’s instructions when using a pressure canner and to use only canners specifically designed for pressure canning. Do not use pressure cookers, as they are not designed for the longer processing times required for canning.
Choosing the right canner is the first step toward safe canning. Carefully consider the types of foods you plan to preserve to determine whether you need a boiling water bath canner or a pressure canner (or both!).
Canning Jars: The Vessels of Preservation
Canning jars are specially designed glass jars that can withstand the high temperatures of the canning process. They are available in various sizes, from small jelly jars to quart jars, to suit different needs. It’s vital to use jars specifically designed for canning; repurposed jars, like mayonnaise jars, are not tempered to withstand the heat and pressure, and can break during processing.
The two most common brands of canning jars are Ball and Kerr, but other reputable brands are also available. Ensure that the jars you purchase are in good condition, free from chips or cracks, especially around the rim.
Lids and Rings: Sealing the Deal
Canning lids and rings are essential for creating an airtight seal that prevents spoilage. Canning lids have a flat metal disc with a rubber sealing compound around the edge. These lids are single-use only; once they have been used for canning, they cannot be reused. The metal rings, also known as screw bands, are used to hold the lids in place during processing. These rings can be reused, but should be free from rust and dents.
Always purchase new lids for each canning session to ensure a proper seal. Inspect the rings for any damage before use. A properly sealed jar is crucial for safe food preservation.
Jar Lifter: A Safe Handling Tool
A jar lifter is a specially designed tool for safely lifting hot jars out of the canner. It has rubber-coated tongs that grip the jar securely without damaging it. Using a jar lifter is crucial to avoid burns and prevent dropping the jars. Trying to lift hot jars with regular kitchen tongs or your bare hands is extremely dangerous.
Canning Funnel: Avoiding Mess and Waste
A canning funnel is a wide-mouthed funnel that sits on top of the jar, making it easier to fill the jar without spilling. This is especially helpful when dealing with jams, jellies, and other sticky substances. A canning funnel helps to maintain a clean jar rim, which is vital for a proper seal.
Bubble Remover/Headspace Tool: Ensuring Proper Headspace
A bubble remover, often combined with a headspace tool, is a handy tool for removing air bubbles from the filled jars before sealing. Headspace is the empty space between the top of the food and the lid. Proper headspace is crucial for creating a vacuum seal during processing. The bubble remover tool is usually a flat, non-reactive utensil (like plastic or rubber) used to gently release trapped air bubbles. The headspace tool is used to measure the correct amount of headspace, which varies depending on the type of food being canned.
Additional Useful Canning Tools
While the tools above are essential, several other tools can make the canning process easier, more efficient, and more enjoyable.
Kitchen Scale: Accurate Measurements
Accuracy is paramount in canning, especially when it comes to recipes involving pectin or precise ingredient ratios. A kitchen scale ensures that you are using the correct amount of each ingredient, which is crucial for proper setting and preservation.
Measuring Cups and Spoons: Precision in Preparation
Using accurate measuring cups and spoons is essential for following canning recipes precisely. Both liquid and dry measuring cups are important. It’s best to use measuring cups and spoons designed for cooking, as they are more accurate than everyday tableware.
Ladle: Efficient Filling
A ladle is a large spoon with a deep bowl, perfect for scooping and pouring liquids and semi-solid foods into the canning jars. A ladle with a long handle is particularly useful for reaching into large pots.
Timer: Precise Processing Times
Accurate timing is vital for safe canning. A kitchen timer ensures that you process the jars for the correct amount of time, which is crucial for killing harmful bacteria and creating a proper seal. Most canners have the timer integrated, but if not, a reliable kitchen timer is necessary.
Thermometer: Monitoring Temperature
A thermometer is essential for monitoring the temperature of jams and jellies to ensure they reach the proper setting point. It can also be useful for monitoring the temperature of the water in a boiling water bath canner.
Food Mill or Blender: Smoothing Things Out
A food mill or blender can be useful for pureeing fruits and vegetables for sauces, jams, and other canned goods. A food mill is particularly helpful for removing seeds and skins from tomatoes and other fruits.
Cutting Board and Knives: Preparation is Key
A good cutting board and a set of sharp knives are essential for preparing fruits and vegetables for canning. Having the right tools for chopping, slicing, and dicing will make the process much easier and more efficient.
Colander or Strainer: Washing and Draining
A colander or strainer is necessary for washing and draining fruits and vegetables before canning. It’s also useful for separating solids from liquids when making sauces or jams.
Apron: Staying Clean
Canning can be a messy process, so an apron is a must-have to protect your clothes from spills and splatters.
Safety Gear for Canning
Safety should always be your top priority when canning. In addition to using the right equipment, it’s also important to wear appropriate safety gear.
Oven Mitts or Heat-Resistant Gloves: Protecting Your Hands
Oven mitts or heat-resistant gloves are essential for handling hot jars and pots. They will protect your hands from burns and make it easier to grip hot items.
Eye Protection: Shielding Your Eyes
Wearing safety glasses or goggles can protect your eyes from splatters and steam. This is especially important when using a pressure canner.
Cleaning Supplies: Maintaining a Sanitary Environment
Maintaining a clean and sanitary environment is crucial for safe canning.
Dish Soap and Water: Basic Cleaning
Wash all jars, lids, and rings with hot, soapy water before using them. Rinse them thoroughly and keep them hot until ready to fill.
Sanitizing Solution: Extra Protection
You can sanitize your jars and lids by boiling them in water for 10 minutes before filling. This will help to kill any remaining bacteria and ensure a safe product.
Clean Towels: Drying and Wiping
Have plenty of clean towels on hand for drying jars, wiping up spills, and keeping your work area clean.

Final Thoughts: Canning with Confidence
Canning is a rewarding and fulfilling activity that allows you to preserve the flavors of the season and enjoy homemade goodness year-round. By investing in the right equipment and following safe canning practices, you can confidently create delicious and safe preserved foods for yourself and your family.
What type of canner do I need to buy to start canning?
The type of canner you need depends on the type of food you’re planning to preserve. For high-acid foods like fruits, jams, jellies, pickles, and tomatoes with added acid (like lemon juice or vinegar), a boiling water bath canner is sufficient. These canners are typically large pots with a rack inside to keep the jars from sitting directly on the bottom of the pot, ensuring even heating.
However, for low-acid foods such as vegetables, meats, and poultry, a pressure canner is essential. Pressure canners reach higher temperatures than boiling water canners, which is necessary to kill harmful bacteria like botulism that can thrive in low-acid environments. Ensure the pressure canner is specifically designed for canning and not just a pressure cooker, as canning-specific models maintain consistent pressure and temperature throughout the processing time. Modern electric pressure canners made specifically for canning can be very convenient.
What are the essential canning tools beyond a canner?
Beyond the canner itself, several other tools are essential for safe and efficient canning. A jar lifter is crucial for safely removing hot jars from the canner without burning yourself. You’ll also need a wide-mouth funnel to easily fill jars without making a mess, a bubble popper/headspace tool to remove air bubbles from the jars and measure the correct headspace, and a magnetic lid wand to lift sterilized lids from hot water.
Furthermore, a ladle is helpful for transferring hot food into jars, and a timer is absolutely necessary to ensure accurate processing times. A reliable kitchen scale is also vital if you’re following recipes that require precise measurements of ingredients. Don’t forget clean kitchen towels and potholders to protect yourself from the heat.
What kind of jars and lids do I need for canning?
You should use canning jars specifically designed for home canning. These jars are made of tempered glass to withstand the high temperatures of the canning process. Ball and Kerr are the most common brands, and they come in various sizes like pint, quart, and half-pint. Do not reuse commercial jars from store-bought food, as they are not tempered for canning heat and can shatter.
For lids, you must use new, unused canning lids each time you can. Canning lids consist of a flat lid with a sealing compound and a metal band. The bands are reusable but the flat lids are not. The sealing compound on the flat lid creates an airtight seal between the jar and the lid. The bands are used to hold the lid in place during processing and should be removed after the jars have cooled and sealed.
How much will it cost to get started with canning?
The cost to get started with canning can vary widely depending on the type of equipment you choose and whether you already own some of the necessary items. A basic boiling water bath canner set, including jars and essential tools, might cost between $50 and $100. However, a pressure canner is a more significant investment, ranging from $100 to $300 or more, depending on the size and features.
Consider the long-term cost savings of canning your own food compared to buying commercially canned goods. Also, keep in mind the cost of ingredients, such as fruits, vegetables, sugar, vinegar, and spices. You can offset some of the initial cost by starting with a small batch of something simple, like jam, and gradually building up your equipment as you gain experience.
What is the importance of headspace when canning?
Headspace refers to the empty space left between the top of the food and the lid of the jar. Leaving the correct amount of headspace is crucial for achieving a proper seal. Too little headspace can cause food to bubble out during processing, preventing the lid from sealing correctly, and potentially contaminating the sealing surface.
Too much headspace can also be problematic. Although it might seem harmless, it can result in inadequate processing due to the presence of too much air inside the jar. Always follow the headspace recommendations specified in your canning recipe. Typical headspace guidelines range from ¼ inch for jams and jellies to 1 inch for some low-acid foods.
Where can I find reliable canning recipes?
It’s crucial to use reliable, tested canning recipes from trusted sources to ensure food safety. The USDA Complete Guide to Home Canning is a comprehensive resource with detailed instructions and tested recipes for a wide variety of foods. Another excellent source is your local county extension office, which often provides canning classes and resources specific to your region.
Ball Canning also offers a variety of tested recipes on their website and in their canning books. Avoid using recipes from untrusted sources, such as blogs or websites without clearly established food safety expertise. Always follow the recipe exactly, without making substitutions or alterations that could compromise the safety of your canned goods.
What safety precautions should I take when canning?
Safety is paramount when canning. Always thoroughly wash your hands, work surfaces, and canning equipment before starting. Inspect jars for any chips or cracks and discard any that are damaged. Follow the processing times and procedures in your recipe exactly, without shortening or altering them.
Use a jar lifter to safely remove hot jars from the canner. After processing, allow the jars to cool completely before checking for a proper seal. Do not force the lids down; a proper seal will be concave and will not flex when pressed. If a jar does not seal, you can either reprocess it with a new lid within 24 hours or refrigerate it for immediate use. Always store canned goods in a cool, dark, and dry place.
