Why Can Blueberries for Pie Filling?

Canning blueberries for pie filling is worth the effort for several reasons.
 

1. You Control the Ingredients

When you can blueberries for pie filling yourself, you decide how much sugar goes in.
 
Store-bought fillings often contain corn syrup, artificial thickeners, and preservatives you don’t need.
 
Homemade filling is just blueberries, sugar, lemon juice, and a little Clear Jel or cornstarch.
 

2. Fresh Flavor All Year

Blueberries are in season for only a few short weeks in most regions.
 
When you can blueberries for pie filling, you capture that peak-season taste and lock it into jars.
 
Come December, you can bake a pie that tastes like July.
 

3. It Saves Money

Buying blueberries in bulk when they’re cheap and canning them is far more affordable than buying pre-made filling.
 
If you grow your own blueberries, canning is basically free.
 

How to Can Blueberries for Pie Filling Step by Step

Learning how to can blueberries for pie filling comes down to a few key steps.
 
Follow these carefully and you’ll have shelf-stable jars ready in no time.
 

1. Gather Your Tools and Ingredients

You’ll need a water bath canner, mason jars, lids, and bands.
 
For the filling itself, grab about 6 quarts of fresh blueberries, 6 cups of sugar, 2 1/4 cups of Clear Jel, 7 cups of water, and 1/2 cup of lemon juice.
 
Clear Jel is important because it thickens without turning gummy, unlike cornstarch which isn’t recommended for canning.
 

2. Wash and Prep the Blueberries

Rinse your blueberries under cold water and pick out any stems or bruised berries.
 
You don’t need to crush them, but you can lightly mash about a quarter of them to help the filling hold together.
 

3. Make the Filling

In a large pot, whisk the Clear Jel into the sugar, then add water and lemon juice.
 
Cook over medium-high heat, stirring constantly, until the mixture thickens and bubbles.
 
Add the blueberries and cook for another minute, stirring gently so you don’t break them apart.
 

4. Fill the Jars

Ladle the hot filling into sterilized jars, leaving about an inch of headspace.
 
Wipe the rims, add the lids, and screw on the bands until fingertip-tight.
 

5. Process in a Water Bath Canner

Place the jars in your canner, making sure they’re covered by at least an inch of water.
 
Process pints for 30 minutes and quarts for 35 minutes, adjusting for altitude if you live above 1,000 feet.
 

Tips for Canning Blueberries for Pie Filling

A few smart habits make canning blueberries for pie filling much easier.
 

1. Don’t Skip the Lemon Juice

Lemon juice adds acid, which is essential for safe canning and also brightens the flavor.
 

2. Use Clear Jel, Not Cornstarch

Cornstarch breaks down during processing and can make your filling runny or unsafe.
 
Clear Jel is the tested choice for canning blueberries for pie filling.
 

3. Let Jars Cool Undisturbed

After processing, leave your jars on a towel for 12 to 24 hours.
 
You’ll hear that satisfying ping as the lids seal.
 

4. Check the Seals Before Storing

Press the center of each lid; if it doesn’t pop back, it’s sealed.
 
Any jars that didn’t seal should go straight into the fridge and be used within a few weeks.
