Boiling jars is a necessary step when making jam in order to sterilize them and prevent the growth of any harmful bacteria that could cause spoilage. This process is crucial to ensuring that your jam lasts as long as possible, without the need for preservatives.
According to the National Center for Home Food Preservation, “sterilizing empty jars is the first step in preserving foods.” The USDA recommends boiling jars for at least 10 minutes in order to ensure that they are sterile. This is especially important for low-acid foods like jams and jellies, which are more susceptible to bacterial growth.
In addition to boiling the jars, it’s also important to make sure they are properly sealed to prevent any contaminants from entering the jar. This can be done by using new lids and ensuring that they are tightly screwed on.
While it may seem like an extra step, boiling jars is a small price to pay for the peace of mind that comes with knowing that your food is safe to eat. As Julia Child once said, “Cooking is like love; it should be entered into with abandon or not at all.”
Here are some other interesting facts about jam making:
Jams and jellies have been around for thousands of years, with evidence of ancient Egyptians preserving fruit as early as 1500 BC.
The percentage of fruit in jam is regulated by the FDA; in order to be labeled as “jam,” it must contain at least 45% fruit.
The highest recorded amount of jam eaten in one sitting is 1.5 kg (3.3 lbs), according to the Guinness Book of World Records.
One of the most popular jam flavors in the world is strawberry, followed closely by raspberry and blackcurrant.
Some of the longest-lived jams in history include a 42-year-old jar of jam from the UK and a 125-year-old jar of plum jam from Australia.
To summarize, boiling jars is an essential step when making jam to ensure that the jars are sterile and free from any harmful bacteria that could cause spoilage. While it may seem like an extra step, it’s a small price to pay to ensure that your food is safe to eat. As with all cooking, it’s important to approach it with care and attention to detail, as Julia Child famously said.

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.

Do you need to boil jam jars after filling?
As a response to this: Yes you should boil them if you want them to be shelf stable, otherwise you run the risk of botulism spores taking hold in the jars (or other food poisoning). This is called water bath canning. I recently made some pie filling this way (which is basically jam) and there were no explosions.

Why do jars of jams need to be processed?
As an answer to this: Processing your jars of jams helps ensure that they won’t spoil on you: More complete removal of oxygen from the headspace also offers some longer protection from undesirable color and flavor changes with some types of fruit products. The canning process is therefore a more foolproof method of making jams and jellies that will not spoil.”
