Making canned fruit jam is a simple and rewarding process that allows you to enjoy your favorite fruits throughout the year. With a few basic ingredients and some simple equipment, you can create delicious homemade jam that’s perfect for topping toast, yogurt, or using as a filling for cakes and pastries. In this article, we’ll take you through the step-by-step process of making canned fruit jam, including the necessary ingredients, equipment, and techniques.
Understanding the Basics of Jam Making
Before we dive into the process of making canned fruit jam, it’s essential to understand the basics of jam making. Jam is a type of fruit preserve made from crushed or puréed fruit, sugar, and sometimes pectin. Pectin is a natural occurring substance found in the cell walls of fruits, particularly in the skin and core of apples and citrus fruits. It acts as a gelling agent, helping to thicken the jam and give it a firm set.
There are several types of jam, including:
- Fruit jam: Made with crushed or puréed fruit, sugar, and sometimes pectin.
- Fruit preserves: Made with whole or large pieces of fruit, sugar, and sometimes pectin.
- Marmalade: Made with citrus fruits, sugar, and water.
- Jelly: Made with fruit juice, sugar, and pectin.
Choosing the Right Fruit
The type of fruit you choose will depend on the flavor and texture you want to achieve. Some popular fruits for making jam include:
- Strawberries: Sweet and flavorful, strawberries make a delicious jam that’s perfect for topping toast or yogurt.
- Raspberries: Tart and tangy, raspberries make a lovely jam that’s great for using as a filling for cakes and pastries.
- Blueberries: Sweet and bursting with antioxidants, blueberries make a delicious jam that’s perfect for topping pancakes or waffles.
- Peaches: Sweet and juicy, peaches make a delicious jam that’s perfect for topping toast or using as a filling for cakes and pastries.
When choosing fruit, make sure to select fruits that are ripe but still firm. Avoid using overripe or mushy fruit, as it can make the jam too soft and runny.
Preparing the Ingredients and Equipment
Before you start making your canned fruit jam, you’ll need to prepare the ingredients and equipment. Here’s what you’ll need:
- 2 cups of fresh or frozen fruit
- 1 cup of granulated sugar
- 1/4 cup of water
- 1 tablespoon of lemon juice
- 1 package of pectin (optional)
- A large pot
- A strainer or food mill
- A glass jar with a lid and band
- A canning funnel
- A clean towel or paper towels
Preparing the Fruit
Wash the fruit thoroughly and remove any stems, leaves, or pits. If using frozen fruit, allow it to thaw first. Crush or purée the fruit using a potato masher or blender, depending on the desired texture.
Preparing the Sugar and Pectin
Measure out the sugar and pectin (if using) into separate bowls. Make sure to use a digital scale to get accurate measurements.
Preparing the Equipment
Wash the pot, strainer or food mill, and glass jar in hot soapy water, and rinse thoroughly. Sterilize the equipment by submerging it in boiling water for 10-15 minutes.
Making the Jam
Now that you’ve prepared the ingredients and equipment, it’s time to make the jam. Here’s a step-by-step guide:
Combining the Fruit and Sugar
In a large pot, combine the crushed or puréed fruit, sugar, and lemon juice. Heat the mixture over medium heat, stirring occasionally, until the sugar has dissolved.
Adding the Pectin (Optional)
If using pectin, stir it in according to the package instructions. Pectin helps to thicken the jam and give it a firm set.
Bringing the Mixture to a Boil
Bring the mixture to a boil, stirring frequently, until it reaches 220°F on a candy thermometer. This should take about 20-25 minutes.
Reducing the Heat and Simmering
Reduce the heat to medium-low and simmer the mixture for 10-15 minutes, or until it has thickened and passed the “wrinkle test”. To perform the wrinkle test, place a small spoonful of the jam on a chilled plate and let it cool to room temperature. If the jam wrinkles when pushed with your finger, it’s ready.
Canning the Jam
Now that you’ve made the jam, it’s time to can it. Here’s a step-by-step guide:
Preparing the Canning Equipment
Wash the canning funnel and glass jar in hot soapy water, and rinse thoroughly. Sterilize the equipment by submerging it in boiling water for 10-15 minutes.

Use the canning funnel to fill the glass jar with the jam, leaving about 1/4 inch of headspace.
Removing Air Bubbles
Use a non-metallic utensil, such as a plastic spatula, to remove any air bubbles from the jar.
Adding the Lid and Band
Place the lid and band on the jar, making sure they’re securely tightened.
Processing the Jar
Place the jar in a large pot or canner, making sure it’s covered by at least 1 inch of water. Bring the water to a boil and process the jar for 10-15 minutes, adjusting for altitude as necessary.
Removing and Cooling the Jar
Remove the jar from the pot or canner and let it cool to room temperature, undisturbed, for 12-24 hours.
Storing the Jam
Once the jar has cooled, store it in a cool, dark place. The jam will keep for up to 12 months in the pantry, or up to 2 years in the freezer.
Checking the Seal
Before storing the jam, make sure to check the seal by pressing on the top of the lid. If the lid does not move and the seal is tight, the jar is sealed properly.
Tips and Variations
Here are some tips and variations to help you make the most of your canned fruit jam:
- Use a variety of fruits to create unique flavor combinations.
- Add spices, such as cinnamon or nutmeg, to give the jam an extra boost of flavor.
- Use honey or maple syrup instead of granulated sugar for a different flavor profile.
- Make a low-sugar jam by using less sugar or substituting with a natural sweetener like stevia.
By following these steps and tips, you can create delicious homemade canned fruit jam that’s perfect for topping toast, yogurt, or using as a filling for cakes and pastries. Happy jam making!
What are the essential ingredients and equipment needed to make canned fruit jam?
To make canned fruit jam, you will need a few essential ingredients, including fresh or frozen fruit of your choice, granulated sugar, lemon juice, and pectin (optional). You will also need some basic equipment, such as a large pot, a strainer, a glass jar with a lid, and a water bath canner. Additionally, you may want to have some extra tools on hand, such as a candy thermometer and a jar lifter.
Having the right equipment and ingredients is crucial to making high-quality canned fruit jam. Make sure to choose fresh and flavorful fruit, and use a good quality sugar that will help to bring out the natural sweetness of the fruit. If you are using pectin, be sure to follow the instructions on the package carefully, as too much pectin can result in a jam that is too thick and gel-like.
How do I prepare the fruit for making canned fruit jam?
Preparing the fruit is an important step in making canned fruit jam. Start by washing the fruit thoroughly and removing any stems, leaves, or other debris. Next, chop or crush the fruit to release its natural juices and help it to cook down more quickly. If you are using a fruit that is high in pectin, such as citrus or apples, you may want to add a little water to the pot to help the fruit cook down more smoothly.
Once the fruit is prepared, you can add it to the pot along with the sugar, lemon juice, and pectin (if using). Bring the mixture to a boil, stirring occasionally, and then reduce the heat and let it simmer until the fruit has broken down and the mixture has thickened. Be sure to stir the mixture frequently to prevent it from sticking to the bottom of the pot.
What is the role of pectin in making canned fruit jam?
Pectin is a natural occurring substance found in the cell walls of fruit, particularly in the skin and core of apples and citrus fruits. It acts as a gelling agent, helping to thicken the jam and give it a firm, jelly-like texture. If you are using a fruit that is low in pectin, such as strawberries or raspberries, you may need to add some commercial pectin to the mixture to help it to set properly.
When using pectin, be sure to follow the instructions on the package carefully, as too much pectin can result in a jam that is too thick and gel-like. You can also use natural pectin sources, such as lemon juice or apple cider, to help to thicken the jam. However, keep in mind that these methods may not be as effective as using commercial pectin.
How do I know when the jam is ready to be canned?
To determine if the jam is ready to be canned, perform a simple test by placing a small amount of the jam on a chilled plate. Let it cool to room temperature, then gently push the jam with your finger. If the jam is set and has a firm, jelly-like texture, it is ready to be canned. If it is still runny or too soft, continue to simmer the mixture for a few more minutes and test it again.
Another way to test the jam is to use a candy thermometer. Bring the mixture to a boil, then reduce the heat and let it simmer until it reaches 220°F on a candy thermometer. This is the ideal temperature for canning jam, as it ensures that the jam is hot enough to kill off any bacteria and create a vacuum seal in the jar.
What is the proper way to can the jam to ensure it is safe to eat?
To can the jam safely, you will need to use a water bath canner. Start by preparing the jars and lids according to the manufacturer’s instructions. Fill the hot, sterilized jars with the jam, leaving about 1/4 inch of headspace at the top. Remove any air bubbles by running a non-metallic utensil, such as a plastic spatula, around the inside of the jar.
Next, place the lids on the jars and screw on the rings until they are just finger-tight. Process the jars in a boiling water bath for 10-15 minutes, adjusting for altitude as necessary. Remove the jars from the canner and let them cool to room temperature, undisturbed, for 12-24 hours. Check the seals after 24 hours and store the jars in a cool, dark place.
How long does homemade canned fruit jam last?
Homemade canned fruit jam can last for up to 12 months when stored properly in a cool, dark place. It’s essential to check the seals regularly to ensure that they are still tight and that the jam is not spoiled. If you notice any signs of spoilage, such as mold, yeast, or an off smell, discard the jam immediately.
To extend the shelf life of your homemade canned fruit jam, be sure to follow safe canning practices and store the jars in a cool, dark place. You can also store the jam in the refrigerator or freezer to extend its shelf life. However, keep in mind that the jam may not last as long as store-bought jam, which has preservatives to extend its shelf life.
Can I customize the recipe to make different flavors of jam?
Yes, you can customize the recipe to make different flavors of jam by using different types of fruit, spices, and flavorings. For example, you can add a cinnamon stick to the pot when making apple jam, or use a flavored extract, such as almond or vanilla, to give the jam a unique flavor. You can also experiment with different combinations of fruit to create unique flavor profiles.
When customizing the recipe, be sure to adjust the amount of sugar and pectin accordingly, as different fruits have varying levels of natural sweetness and pectin. You can also add a little lemon juice to help to bring out the flavors of the fruit and balance the sweetness of the jam. Experiment with different flavor combinations to find the one that you enjoy the most.
