Boiling water canning is a method of preserving food in jars by boiling them in hot water for a set amount of time, sealing the jars and creating a vacuum seal to prevent spoilage.
So let’s look deeper
Boiling water canning is a method of preserving food that has been used for centuries. This traditional method involves processing food in glass jars that are submerged in boiling water for a set amount of time. The heat from the boiling water kills off any bacteria in the food, and creates a vacuum seal in the jar, helping to prevent spoilage.
According to the National Center for Home Food Preservation, boiling water canning is suitable for high-acid foods like fruits, tomatoes, and pickles. These foods have a pH of 4.6 or lower, which helps to prevent the growth of botulism bacteria. Low-acid foods like meats and vegetables require more intense processing methods, such as pressure canning, to ensure their safety.
Boiling water canning is a simple process that can be done at home with basic equipment. All you need is a large pot, some canning jars, and a few basic utensils. The process typically involves heating the food in the jars, sealing the jars with lids and bands, and then submerging the jars in boiling water for a certain amount of time. Once the jars are removed from the water and cooled, the vacuum seal will keep the food safe for several months.
As put by the food writer and cookbook author, Marisa McClellan: “Canning is not a one-size-fits-all proposition. Each type of food requires a slightly different method of preservation in order to ensure safety and peak flavor.”
Interesting facts about boiling water canning include:
- The process was first developed by French chef Nicolas Appert in the early 1800s, when he discovered that heating food in sealed jars helped to preserve it for longer periods of time.
- Canning became popular in the United States during the mid-1800s, when it was seen as a way to prevent foodborne illness and ensure a steady supply of food for troops during wartime.
- The modern canning jar with a two-piece lid was not introduced until the early 20th century, when it was developed by the Ball Corporation.
- Today, there are many different resources available for home canners, including books, websites, and even classes where you can learn more about the process.
- As with any preservation method, it is important to follow safe canning practices to avoid the risk of botulism or other foodborne illnesses. The National Center for Home Food Preservation offers a wealth of information on safe canning practices and recipes.
Here is a table that shows the recommended processing times for boiling water canning of some common fruits:
| Fruit | Processing Time (in minutes) |
|---|---|
| Peaches | 25 |
| Pears | 25 |
| Cherries | 25-30 |
| Apples | 20-25 |
| Plums | 20-25 |
In conclusion, the boiling water canning process is a simple and effective way to preserve high-acid foods like fruits and pickles. By following safe canning practices and using the proper processing times, you can enjoy the taste of fresh, seasonal produce all year round.

What Is Water Bath Canning? Water bath canning is a method of food preservation for acidic foods that uses pressure, created by boiling water, to create an environment within glass jars which prevents harmful bacteria from growing on the food.
The lid lifter is designed for removing hot canning lids and rings from the boiling water used to sterilize them. They can be a simple magnet on a stick, but the Prepworks lifter has a ring on the end, making it a bit easier to hold.

In “Canning Using the Boiling-Water Method,” viewers learn about the boiling-water method of canning, which is recommended for canning acidic foods including jams, jellies, chutneys, and lemon curds. The method involves preparing jars, lids, and rings, ladling the recipe into the jars, processing the jars, and allowing them to cool before storing them in a cool place. A canner, canning tongs, and a canning funnel are essential tools for this method, while a lid lifter is useful but not necessary.

The easy solution is to use any deep pan or stock pot that is deep enough to cover the jars and a rack with one to two inches of water. Remember to allow some additional space for water to boil rapidly without going over the edge of the pan.
