Canning at home is a great way to preserve fresh produce and enjoy your favorite foods year-round. Not only does it allow you to save money and reduce food waste, but it also gives you control over the ingredients and nutritional content of your food. In this article, we’ll take you through the basics of canning at home, including the equipment and supplies you’ll need, the different types of canning methods, and some tips for getting started.
Understanding the Basics of Canning
Before you start canning, it’s essential to understand the basics of the process. Canning involves packing food into airtight containers, known as jars, and heating them to a high temperature to kill off any bacteria and other microorganisms that may be present. This process, known as sterilization, is crucial for ensuring that your canned goods are safe to eat.
There are two main types of canning methods: water bath canning and pressure canning. Water bath canning is used for high-acid foods, such as fruits, jams, and pickles, while pressure canning is used for low-acid foods, such as meats, vegetables, and soups.
Water Bath Canning
Water bath canning is a simple and easy-to-use method that’s perfect for beginners. It involves submerging your jars in a large pot of boiling water, where they’re heated to a temperature of at least 212°F (100°C). This method is ideal for high-acid foods, which are naturally acidic and therefore less susceptible to spoilage.
To use the water bath canning method, you’ll need a large pot with a rack in the bottom. This rack allows you to place your jars off the bottom of the pot, where they can be fully submerged in water. You’ll also need a lid for the pot, as well as a set of canning jars and lids.
Equipment Needed for Water Bath Canning
- Large pot with a rack in the bottom
- Lid for the pot

Preparing Your Food
Once your jars and lids are prepared, it’s time to prepare your food. This involves washing, chopping, and cooking your ingredients, as well as packing them into your jars.
When packing your jars, it’s essential to leave a small amount of headspace at the top. This allows for expansion during the canning process, and helps to prevent your jars from becoming over-pressurized.
General Guidelines for Packing Jars
- Leave 1/4 inch of headspace for high-acid foods
- Leave 1/2 inch of headspace for low-acid foods
- Use a non-metallic utensil to remove air bubbles
- Wipe the rim of the jar with a clean, damp cloth
Processing Your Jars
Once your jars are packed and sealed, it’s time to process them. This involves heating them to a high temperature, either using a water bath canner or a pressure canner.
When processing your jars, it’s essential to follow a tested recipe and procedure. This ensures that your jars are heated to a safe temperature, and that they’re properly sterilized.
General Guidelines for Processing Jars
- Process high-acid foods for 10-30 minutes in a water bath canner
- Process low-acid foods for 30-60 minutes in a pressure canner
- Use a timer to ensure that your jars are processed for the correct amount of time
- Let your jars cool before storing them
Storing Your Jars
Once your jars are processed and cooled, it’s time to store them. This involves placing them in a cool, dark place, such as a pantry or cupboard.
When storing your jars, it’s essential to keep them away from direct sunlight and heat sources. This helps to prevent spoilage and ensures that your jars remain safe to eat.
General Guidelines for Storing Jars
- Store your jars in a cool, dark place
- Keep your jars away from direct sunlight and heat sources
- Check your jars regularly for signs of spoilage
- Use your jars within 12 months
Tips for Getting Started
If you’re new to canning, it’s essential to start with a few simple recipes and procedures. This helps to build your confidence and ensures that you’re producing safe, high-quality canned goods.
Here are a few tips for getting started:
- Start with a simple recipe, such as jam or pickles

What is canning and how does it work?
Canning is a method of preserving food by packing it in airtight containers, known as jars or cans, and heating them to kill off any bacteria or other microorganisms that may be present. This process creates a vacuum seal that prevents new contaminants from entering the container, allowing the food to be stored for long periods of time.
The canning process involves several steps, including preparing the food, packing it into clean, sterilized jars, adding a brine or syrup, and then heating the jars in a boiling water bath or pressure canner. The heat from the water bath or pressure canner kills off any bacteria or other microorganisms that may be present, and the vacuum seal that forms as the jars cool prevents new contaminants from entering the container.
