Ingredients
- 2 cups strawberries, hulled and chopped
- 2 cups raspberries
- 2 cups blueberries
- 2 cups blackberries
- 4 cups granulated sugar
- ¼ cup lemon juice
- 1 package (1.75 ounces) powdered fruit pectin

Step 1: Prepare the Jars
Time: 10 minutes
Intensity: Easy
Wash jars, lids, and bands in hot soapy water.
Rinse thoroughly.
Place jars in hot water or a dishwasher to keep them warm until filling time.
Prepare lids according to the manufacturer’s instructions.
Keeping jars hot helps prevent thermal shock when hot jam is added.
Step 2: Prepare the Berries
Time: 10 minutes
Intensity: Easy
Wash all berries carefully.
Remove stems and hulls where necessary.
Chop larger strawberries into small pieces.
Lightly mash the berries using a potato masher.
Leave some chunks for texture if desired.
Measure berries accurately to ensure proper consistency.
Step 3: Combine Ingredients
Time: 5 minutes
Intensity: Easy
In a large stockpot, combine:
- Strawberries
- Raspberries
- Blueberries
- Blackberries
- Lemon juice
- Pectin
Stir thoroughly.
Place the pot over medium heat.
Step 4: Bring to a Boil
Time: 10 minutes
Intensity: Medium-High
Bring the berry mixture to a full rolling boil while stirring frequently.
A rolling boil is one that cannot be stirred down.
This stage activates the pectin and begins thickening the jam.
Step 5: Add Sugar
Time: 2 minutes
Intensity: Medium
Gradually add the sugar while stirring continuously.
Mix until completely dissolved.
Return the mixture to a full rolling boil.
Continue boiling for 1 minute while stirring constantly.
The mixture should appear glossy and slightly thickened.
Step 6: Test the Jam
Time: 3 minutes
Intensity: Low
Remove the pot from heat.
To test consistency:
Place a small spoonful on a chilled plate.
Allow it to sit for 30 seconds.
Push gently with your finger.
If the surface wrinkles slightly, the jam is ready.
If not, boil for another minute and test again.
Step 7: Fill the Jars
Time: 10 minutes
Intensity: Easy
Using a funnel and ladle, carefully fill hot jars with hot jam.
Leave approximately ¼ inch headspace.
Remove air bubbles using a bubble remover tool.
Wipe rims clean with a damp cloth.
Apply lids and bands until fingertip tight.
Step 8: Process in Water-Bath Canner
Time: 10 minutes
Intensity: Medium
Place filled jars into the water-bath canner.
Ensure jars are covered by at least 1 inch of water.
Bring water to a full boil.
Process for 10 minutes.
Adjust processing time if required for your altitude.
Step 9: Cool the Jars
Time: 12–24 Hours
Intensity: No Heat
Using a jar lifter, carefully remove jars.
Place on a towel-lined counter.
Allow jars to cool undisturbed for 12 to 24 hours.
You may hear the satisfying “pop” of lids sealing.
Step 10: Check Seals and Store
Time: 5 minutes
Intensity: Easy
After cooling:
- Remove screw bands
- Check seals
- Ensure lids do not flex when pressed
Label jars with:
- Product name
- Date canned
Store in a cool, dark pantry.
