What Is Canning?

Canning is the process of preserving food by sealing it in an airtight container and heating it to destroy microorganisms that cause spoilage.

Definition And History

Canning is a food preservation method that involves processing and sealing food in airtight containers, usually glass jars, to ensure it remains safe and fresh for an extended period.

The history of canning dates back to the early 19th century when French inventor Nicolas Appert developed the technique to preserve food for Napoleon’s army.

As the years passed, canning evolved into a popular home preservation method in both rural and urban settings, allowing households to retain harvest bounty during peak seasons while enjoying off-season access to nutritious fruits and vegetables.

In more recent times, canning has become especially appealing to individuals interested in off-grid living as it offers long-term storage solutions without relying on electricity or refrigeration.

Benefits Of Canning

Preserving your own food through canning is not only a fun and rewarding experience but also has many benefits. First, it saves you money by allowing you to buy produce in bulk when it’s in season and preserve it for later use.

Plus, canned foods have a longer shelf life than fresh produce, meaning less waste and fewer trips to the grocery store.

But perhaps the biggest benefit of canning is knowing exactly what goes into your food. By controlling the ingredients and process yourself, you avoid harmful preservatives often found in commercially canned products.

Canning also allows you to enjoy seasonal fruits and vegetables all year round, giving you access to fresh and healthy foods even during winter months.

Types Of Canning Methods

Learn about the two main types of canning methods: water bath canning and pressure canning, and discover which one is best for your food preservation needs.

Water Bath Canning

Water bath canning is a popular method for preserving acidic fruits and vegetables, such as tomatoes, apples, and pickles. The technique involves submerging filled jars in boiling water for a specific amount of time to create an airtight seal that prevents the growth of bacteria.

Water bath canning is relatively easy and requires minimal equipment compared to pressure canning. All you need is a large pot with a lid, racks or towels to keep jars from touching the bottom of the pot, and mason jars fitted with new lids and rings.

However, it’s essential to follow proper safety guidelines when water bath canning since low-acid foods could cause botulism if not processed correctly.

Pressure Canning

Pressure canning is a preserving method that uses high temperatures and pressure to eliminate harmful microorganisms from food. It’s the best option for preserving low-acid foods, such as meats, soups, and vegetables.

To start pressure canning at home, you’ll need a pressure canner that meets safety standards set by the USDA. Additionally, it’s crucial to follow tested recipes and processing times carefully to ensure safe preservation.

Equipment And Supplies Needed For Canning

To get started with canning, you will need a pressure canner or water bath canner, mason jars, lids and bands, jar lifter, canning funnel, and other helpful tools such as a bubble remover and lid lifter.

Pressure Canner

A pressure canner is a must-have tool for anyone interested in home canning. This specific type of canning method uses high pressure and temperature to safely process low-acid foods, such as meat, poultry, seafood, and vegetables.


Unlike water bath canning that uses boiling water, a pressure canner heats the food more thoroughly to destroy bacteria and other microorganisms that can spoil or cause illness.

When choosing a pressure canner, look for one with a safety valve and gauge that release steam if the internal pressure exceeds safe levels. Some popular brands include All American and Presto.

Water Bath Canner

Water bath canning is the most common method for preserving acidic foods like fruit, jams, and pickles. It’s a simple process that involves boiling jars of food in hot water for a set time to kill any bacteria or microorganisms present.

To get started with water bath canning, you’ll need a large pot with a lid, a rack to hold the jars off the bottom of the pot during processing, and specialized tongs to remove hot jars from the water.

Once you’ve filled your jars with prepared fruits or vegetables and sealed them tightly with lids and bands, they’re ready to be processed in simmering water according to specific recipes.

Mason Jars

Mason jars are an essential part of the canning process. These glass jars come in a variety of sizes and are perfect for storing canned goods, such as fruits, vegetables, jams, and pickles.

When choosing mason jars for canning, it’s important to look for ones without any cracks or chips. Also ensure that they’re made specifically for canning as other types of glass may not hold up well under high temperatures.

Mason jars typically come with two-part lids consisting of a flat metal disk with a rubberized coating (the lid) and a separate metal band (the ring) that screws onto the jar to hold the lid securely in place during processing.

Lids And Bands

To properly preserve food, you’ll need to seal it in airtight containers with lids and bands. Mason jars are commonly used, as they’re sturdy and can withstand high temperatures during processing.

Lids come in two types: metal and plastic. Metal lids have a thin rubber lining that creates an airtight seal when processed correctly, whereas plastic lids are reusable but may not create as tight of a seal.

Bands are used to hold the lid in place during processing and storage. It’s important to note that bands should be removed after processing to avoid rusting or warping from heat exposure.

Jar Lifter

A jar lifter is an essential tool in the canning process. It allows you to safely remove hot jars from the canner without risking burned fingers or dropped jars. This tool has special gripping ends that fit snugly under the lip of the jar and provide a secure hold while lifting.

Without one, it’s easy to drop or spill hot jars, which can be dangerous and frustrating.

Canning Funnel

A canning funnel is a must-have tool for any home canner. This special funnel is designed to make it easier to pour hot liquids, like jams and sauces, into jars without making a mess.

The wide mouth of the funnel fits perfectly over the opening of your mason jar, ensuring that everything goes in smoothly and quickly. And because canning funnels are made from heat-resistant materials like stainless steel or plastic, they won’t melt or warp even when exposed to high temperatures.

Other Helpful Tools

Aside from the essential equipment needed for canning, there are other helpful tools that can make the process smoother and easier. One of these is a bubble remover tool, which helps to get rid of air pockets in jars, ensuring proper sealing.

Another useful tool is a lid lifter, which makes it easy to remove hot lids from boiling water without burning your hands. A magnetic lid wand is also handy for retrieving lids from boiling water or sterilizing solution without having to touch them with your hands.

And if you plan on making jams or jellies, a candy thermometer will come in handy for measuring temperature accurately during cooking.

The Canning Process

After preparing your produce, sterilize jars and fill them with food, leaving the appropriate headspace before sealing them with lids and bands.

Choosing And Preparing Produce

To begin the canning process, it is important to choose the right produce. You want to select fruits and vegetables that are in peak condition and free of blemishes or bruises.

This will ensure that you have high-quality canned goods that taste great months down the line. Additionally, it’s crucial to properly prepare your produce before canning.

It’s also essential to make sure you are using a tested recipe when canning your fruits and vegetables. Following a trusted recipe ensures that you safely preserve food without introducing harmful bacteria or contamination during the preparation process.

Some examples of popular recipes for canning include pickles, jams, jellies, salsas, tomato sauce, fruit preserves like peaches and pears as well as soups with meat such as chicken soup or beef stew which last longer by preserving them through home-canning methods like water bath or pressure canning techniques.

Sterilizing Jars

Before filling your jars with produce, it is essential to sterilize them properly. This step will destroy any bacteria or microorganisms that may have contaminated the jars during storage, ensuring a safe and long-lasting final product.

To sterilize jars, you can use either the boiling water or oven methods. In both cases, start by washing the jars in hot soapy water and rinsing thoroughly. For boiling water sterilization, place the clean jars and lids in a large pot filled with enough water to fully submerge them.

Bring the water to a boil over high heat and let boil for 10 minutes before removing from heat. For oven sterilization, place cleaned jars on a baking sheet and bake at 225°F for 10-15 minutes until dry and hot to touch.

Filling And Sealing Jars

After preparing your produce and sterilizing your jars, it’s time to fill and seal them properly. First, use a canning funnel to easily transfer the food into the jar without making a mess.

Leave some headspace at the top of the jar as instructed by your recipe or canning method.

When sealing jars using water bath canning, ensure that you tighten but do not over-tighten the bands as this may affect their ability to create an effective seal during processing.

With pressure canning, be sure to follow manufacturer instructions for ensuring steam escapes from vent pipe before sealing with weighted gauge or locking lid in place. Properly sealed jars will make a popping sound upon cooling down and have no give when pressed inwards at center of lid.

Processing Jars

Processing jars is a crucial step in canning to ensure that the food inside remains safe and shelf-stable. After filling the jars with prepared produce, they need to be processed in either a water bath or pressure canner.

During processing, microorganisms are destroyed by high temperatures, and an airtight seal is created on the jar’s lid. The length of time required for processing depends on several factors such as altitude, jar size, and recipe guidelines.

Once processed, it’s essential to allow the jars to cool slowly before checking their seals and storing them properly.

Cooling And Storing Jars

Once your jars have cooled, check for proper seal by pressing the center of the lid. If it pops up and down, then it did not seal properly and should be stored in the refrigerator or eaten immediately.

Label each jar with the contents, date, and processing method used. Store sealed jars in a cool, dark place away from direct sunlight to prevent discoloration or spoilage.

Properly canned food may last up to a year or more depending on what was canned and how well it was processed.

Safety Tips And Common Mistakes To Avoid

You must always choose safe recipes when canning and ensure proper processing time and temperature to avoid health hazards caused by microorganisms.

Choosing Safe Recipes

It’s essential to choose safe recipes when canning, as unsafe practices can lead to foodborne illness. Always use tested recipes from reputable sources like the National Center for Home Food Preservation or university extension services.

Additionally, follow the recipe directions carefully and don’t make substitutions for ingredients or methods without consulting a trusted source. For example, substituting vinegar for lemon juice in a recipe could change the acidity level and make your canned goods unsafe.

Ensuring Proper Processing Time And Temperature

Proper processing time and temperature are essential to ensuring that your canned food is safe for consumption. Under-processing can lead to the growth of harmful microorganisms, while over-processing can result in a loss of nutrients and flavor.

It’s important to follow recipes carefully, as the required processing time and temperature may vary depending on the type of food being canned and the method used. For example, low-acid foods like meat or vegetables require pressure canning at specific temperatures for a specified amount of time, while high-acid foods like fruits can be safely processed using water bath canning methods.

Always use a reliable source for your recipes, such as those provided by trusted organizations like Ball or National Center for Home Food Preservation.

Checking For Seal Integrity

After the canning process, it’s crucial to check for seal integrity to ensure that your food is safe to eat. One way to do this is by inspecting the lid of the jar. If it’s concave and doesn’t move when pressed, then you have a good seal.

However, if you notice any bulging or leaking from the jar, discard its contents immediately since these are signs that bacteria has grown and caused spoilage. Another way to test for a proper seal is by gently tapping or pressing on the lid; if there’s no sound or movement, then your jar has successfully sealed.

Properly Storing Canned Foods

Once you’ve successfully canned your food, it’s important to store them properly so that they remain safe and delicious for future consumption. It is recommended that canned goods be stored in a cool, dry place away from direct sunlight.

This can be in a pantry or cellar with temperatures ranging between 50-70°F. However, storing jars on metal shelving may lead to rust and weaken the seal over time.

It’s also important to label your cans properly indicating what type of food has been preserved, the date of bottling as well as the expiry date which depends on whether it was water bathed or pressure canned.

Canned foods stored under ideal conditions can last up to one year but it is always good practice to do a visual inspection before consuming just in case signs of spoilage are present such as bulging lids, strong off odors/smells or cloudiness/turbidity of contents.

Recognizing And Avoiding Common Mistakes

To ensure the safety and success of your canning projects, it’s important to recognize and avoid common mistakes. One of the most crucial mistakes is choosing unsafe recipes or not following them precisely.

Another common mistake is not processing jars for the correct amount of time or temperature. This could lead to under-processing, which poses a health hazard due to microorganisms that can cause food poisoning.

It’s essential to follow recommended processing times, whether you’re using water bath canning or pressure canning methods.
