Nothing compares to the taste of homemade blueberry jam.
Making jam at home allows you to control the ingredients.
It also lets you savor the fruits of your labor year-round.
Follow this easy recipe to make your blueberry jam.
We’ll also discover how EVOH packaging can help preserve its quality.
Ingredients
To make a small batch of blueberry jam, you’ll need:
- 4 cups of fresh or frozen blueberries
Both fresh and frozen blueberries work well.
However, fresh ones bring out a brighter and more vibrant flavor.
- 1 cup of granulated sugar
Besides sweetening the jam, sugar acts as a natural preservative.
It can extend its shelf life when stored properly in the fridge or freezer.
- 2 tablespoons of lemon juice
Use both the zest and juice for a tangy flavor and a touch of acidity.
The added acid helps the blueberry jam achieve the right consistency.
- Pinch of salt
A small amount enhances the overall flavor.
Feel free to skip this if you prefer.
- 1 tablespoon of powdered fruit pectin (optional)
Step-by-Step Guide
Step 1: Prepare the Blueberries
Wash the blueberries thoroughly under running water.
If using fresh berries, remove any stems or leaves.
For frozen blueberries, let them thaw to room temperature.
Once cleaned, mash the blueberries slightly using a fork or potato masher.
This step ensures a smooth and consistent texture.
Step 2: Combine Ingredients
In a large saucepan, mix these ingredients:
- mashed blueberries
- sugar
- lemon juice
At this stage, add the fruit pectin if you prefer a thicker consistency.
Stir the mixture well to combine all the ingredients.
Step 3: Cook the Blueberry Jam
Place the saucepan over medium heat and bring the mixture to a boil, stirring constantly.
Once boiling, reduce the heat to low and let it simmer.
Stir frequently to prevent sticking.
The jam should thicken after 15-20 minutes.
Place a small amount on a cold plate; if it holds its shape, the jam is ready.
Step 4: Sterilize the Containers
While the jam is cooking, prepare your jars or bottles.
To sterilize them, boil them in water for 10 minutes.
Then, let them air-dry on a clean towel.
Step 5: Pour and Seal
Carefully ladle the hot jam into the sterilized containers.
Leave about half an inch of space at the top.
Seal the jars tightly.
At this stage, you can consider using EVOH packaging for longer-lasting freshness.
Storage Tips
- Store sealed jars in a cool, dark place for up to a year.
- Once opened, keep the blueberry jam in the refrigerator.
- Consume within a few months.
- Always use a clean spoon to extend its freshness.
Why Skip Pectin?
Blueberries naturally contain pectin, especially when slightly under-ripe.
Lemon juice also enhances the gelling process.
Skipping commercial pectin allows for a more intense fruit flavor as the moisture reduces during cooking.
However, skipping it is optional.
Why Choose EVOH Packaging for Blueberry Jam?
EVOH (Ethylene Vinyl Alcohol) packaging is an excellent choice for preserving homemade blueberry jam.
This advanced material is known for its remarkable oxygen-barrier properties.
It can help maintain the jam’s freshness and flavor over time.
Here’s why EVOH packaging is a smart choice:
Oxygen Barrier
Exposure to oxygen can degrade the quality of food products.
It can also lead to:
- spoilage
- discoloration
- changes in taste
EVOH’s molecular structure creates an almost impenetrable barrier to oxygen.
It can keep the jam fresh and prevent bacterial growth.
Multi-Layer Technology
EVOH is often incorporated between the inner and outer layers of plastic packaging.
This multilayer design ensures that the packaging remains durable while providing maximum protection against environmental factors.
A thin adhesive layer binds the EVOH barrier to the plastic, ensuring it stays intact.
Protection Against Other Gasses
Aside from oxygen, EVOH also blocks carbon dioxide and other gasses that can affect the blueberry jam’s shelf life.
This feature is particularly helpful for preserving blueberry jam’s natural flavor and aroma.
Sustainability
Many EVOH-based packaging solutions are recyclable.
They align with environmentally conscious practices.
By choosing EVOH containers, you’re ensuring quality preservation.
You also make an eco-friendly choice.
Tips for Using EVOH Packaging at Home
Sterilization
Ensure the EVOH containers are properly sterilized before use.
This step is important for maintaining the jam’s quality.
Sealing
After filling the containers, seal them tightly to prevent air entry.
Storage
Store the jars in a cool place to further extend their shelf life.
Helpful Tips for Canning Blueberry Jam
Streamline Your Process
Save time by prepping lids, sterilizing jars, and cooking the jam simultaneously.
Keep your canning kettle hot while filling jars so it reheats faster.
Use Bottled Lemon Juice
Opt for bottled lemon juice instead of fresh.
Its consistent acidity helps ensure your jam is stable and safe during storage.
Prioritize Safety
Be cautious of hot surfaces.
Use oven mitts or a jar lifter to handle jars and lids.
A magnetic lid lifter can make the process safer and smoother.
Start Timing at a Rolling Boil
Begin the canning time only when the water reaches a full rolling boil.
Some canners have a thermometer for ease.
Boiling times may also vary depending on your altitude.
Serving Suggestions
Blueberry jam is incredibly versatile and can be enjoyed in numerous ways:
- Spread it on freshly toasted bread or scones.
- Use it as a filling for pastries and cakes.
- Add a spoonful of yogurt or oatmeal for a burst of flavor.
- Pair it with cheese and crackers for an elegant snack.
Various Storage Options
Canning Method for Long-Term Storage
Once jars are processed and sealed, remove the rings to avoid false sealing.
Store the jars in a cool, dark place for up to one year.
If any jars fail to seal, refrigerate them.
Then, use them within a few weeks.
Freezing Method
For longer storage, transfer the jam into freezer-safe containers.
Also, leave space for expansion.
Store in the freezer for up to 4 months.
When ready to use, thaw in the refrigerator and consume within 3-4 weeks.
Refrigeration Method
If you prefer not to can the jam, refrigerate it instead.
This recipe yields approximately 9 jars, so plan for storage space.
Refrigerated blueberry jam should remain fresh for 3-4 weeks.
