Why You Should Can Blackberry Pie Filling

Canning blackberry pie filling is one of the smartest ways to preserve this summer fruit.
 
Here’s why it’s worth the effort:
 

1. Enjoy Blackberries Year-Round

When you can blackberry pie filling, you capture that fresh-picked flavor and lock it in a jar.
 
Come December, you can open a jar, pour it into a crust, and taste summer again.
 
No defrosting, no sad frozen berries, just ready-to-use filling.
 

2. Save Money and Reduce Waste

If you have more blackberries than you can eat, canning blackberry pie filling prevents them from going bad.
 
Instead of tossing spoiled fruit, you turn it into something shelf-stable.
 
Plus, homemade pie filling costs way less than store-bought cans.
 

3. Control the Ingredients

When you can blackberry pie filling yourself, you decide how much sugar goes in.
 
You can skip artificial preservatives and thickeners you can’t pronounce.
 
That means a cleaner, better-tasting pie filling for you and your family.
 

How to Can Blackberry Pie Filling: Step-by-Step

Learning how to can blackberry pie filling is straightforward once you know the process.
 
Just follow these steps carefully.
 

1. Gather Your Ingredients and Equipment

To can blackberry pie filling, you’ll need about 6 cups of fresh blackberries, 1 cup of sugar, ¼ cup of lemon juice, and ¼ cup of ClearJel (a modified cornstarch that holds up to canning heat).
 
You’ll also need a water bath canner, mason jars, lids, and bands.
 
Don’t substitute regular cornstarch, because it breaks down during processing and your filling will turn soupy.
 

2. Prepare the Blackberries

Rinse your blackberries gently under cool water and drain them well.
 
Remove any stems or leaves, and discard mushy or moldy berries.
 
If you’re using frozen blackberries, thaw them first and save the juice.
 

3. Cook the Filling

In a large pot, combine the blackberries, sugar, and lemon juice.
 
Bring the mixture to a boil over medium heat, stirring occasionally.
 
In a separate bowl, whisk the ClearJel with a little cold water until smooth, then stir it into the boiling berries.
 
Cook for 1 to 2 minutes until the filling thickens, then remove from heat.
 

4. Fill Your Jars

Ladle the hot filling into sterilized jars, leaving about 1 inch of headspace.
 
Use a bubble popper or a thin spatula to remove air bubbles.
 
Wipe the rims with a clean, damp cloth, then place the lids and bands on finger-tight.
 

5. Process in a Water Bath Canner

Lower the jars into boiling water, making sure they’re covered by at least 1 inch.
 
Process pint jars for 30 minutes and quart jars for 35 minutes (adjust for altitude if needed).
 
When time’s up, turn off the heat and let the jars sit for 5 minutes before removing them.
 

6. Cool and Check the Seals

Place the jars on a towel-lined counter and let them cool undisturbed for 12 to 24 hours.
 
You’ll hear that satisfying “pop” as the lids seal.
 
Once cool, press the center of each lid—if it doesn’t flex, you’ve successfully canned blackberry pie filling.
 

Tips for Perfect Canned Blackberry Pie Filling

If you want to can blackberry pie filling that tastes amazing and stays safe, keep these tips in mind.
 

1. Don’t Skip the Lemon Juice

Lemon juice adds necessary acid to the filling, which helps with safe canning.
 
It also brightens the flavor so your blackberry pie filling doesn’t taste flat.
 

2. Use ClearJel, Not Cornstarch

Regular cornstarch isn’t approved for canning because it thickens but then breaks down.
 
ClearJel is made specifically for canned pie fillings and keeps its texture.
 

3. Adjust for Altitude

If you live above 1,000 feet, you’ll need to add processing time.
 
Check your local extension office for the correct adjustments when you can blackberry pie filling.
