Cooking time:
- 30 minutes
Total time:
- Approximately 1 hour
Ingredients
Fruit Base
- 4 cups fresh strawberries, hulled and chopped
- 4 cups fresh cranberries
- ½ cup fresh orange juice
- 1 tablespoon orange zest
Sweeteners
- 5 cups granulated sugar
- ¼ cup honey
Sourdough Component
- 1 cup sourdough discard (unfed starter)
The discard should be:
- Fresh
- Free from mold
- Pleasantly sour smelling
Discard that is up to one week old and refrigerated works well.
Spices
- 1 teaspoon ground cinnamon
- ¼ teaspoon ground cloves
- ¼ teaspoon nutmeg
- ¼ teaspoon allspice
- ¼ teaspoon ground ginger
Thickening
- 1 package (1.75 ounces) powdered fruit pectin
Optional Flavor Enhancers
- 1 teaspoon vanilla extract
- 1 tablespoon lemon juice
Equipment Needed
- Large heavy-bottomed stockpot
- Wooden spoon
- Potato masher
- Measuring cups
- Canning funnel
- Jar lifter
- Water bath canner
- Sterilized half-pint jars
- New canning lids and bands
Step 1: Prepare the Fruit
Wash strawberries thoroughly.
Remove:
- Stems
- Leaves
- Bruised portions
Chop into small pieces.
Rinse cranberries and discard any damaged berries.
Wash the orange and zest it carefully.
Juice the orange and measure ½ cup juice.
The combination of strawberries and cranberries creates the beautiful ruby-red color that makes Christmas Jam so attractive.
Step 2: Sterilize Jars
Before making the jam, prepare your jars.
- Wash jars in hot soapy water.
- Rinse thoroughly.
- Place jars in simmering water.
- Keep warm until ready to fill.
Prepare lids according to the manufacturer’s directions.
Warm jars help prevent cracking when hot jam is added.
Step 3: Cook the Fruit
Place the following into a large stockpot:
- Strawberries
- Cranberries
- Orange juice
- Orange zest
Cook over medium heat.
Stir frequently.
As the mixture heats:
- Cranberries begin to pop
- Strawberries soften
- Juice releases naturally
Continue cooking for about 10–15 minutes.
The fruit should become soft and fragrant.
Step 4: Mash the Fruit
Using a potato masher:
- Crush the strawberries
- Break open remaining cranberries
You can leave some fruit chunks for texture.
For smoother jam:
- Use an immersion blender briefly
Avoid pureeing completely because some texture improves the finished product.
Step 5: Add the Sourdough Discard
Reduce heat slightly.
Slowly stir in:
- 1 cup sourdough discard
Whisk continuously while adding.
The discard should blend smoothly into the fruit mixture.
Cook for 3–5 minutes.
This step allows the sourdough flavor to integrate with the fruit.
The mixture may become slightly thicker due to the flour present in the starter.
Step 6: Add Pectin
Sprinkle powdered pectin evenly across the fruit mixture.
Stir constantly to avoid lumps.
Increase heat.
Bring the mixture to a full rolling boil.
A rolling boil continues even while stirring.
Once boiling, maintain the boil for one minute.
Step 7: Add Sugar and Honey
Add:
- 5 cups granulated sugar
- ¼ cup honey
Stir continuously until fully dissolved.
Return the mixture to a full rolling boil.
Boil hard for exactly one minute.
This timing is important for proper gel formation.
Step 8: Add the Christmas Spices
Remove the pot from heat.
Stir in:
- Cinnamon
- Cloves
- Nutmeg
- Allspice
- Ginger
If using:
- Vanilla extract
- Lemon juice
add them now.
The aroma at this stage is wonderfully festive, combining fruit, citrus, spice, and the subtle tang of sourdough.
Step 9: Test for Gel
To test consistency:
- Place a small plate in the freezer.
- Spoon a little jam onto the cold plate.
- Wait 30 seconds.
- Push gently with your finger.
If the surface wrinkles, the jam is ready.
If not, cook for another minute and test again.
Step 10: Remove Foam
Some foam may form during cooking.
Skim off any foam using a spoon.
Removing foam improves the appearance of the finished jam.
Step 11: Fill the Jars
Using a canning funnel:
Fill hot jars with jam.
Leave:
- ¼ inch headspace
between the jam and the rim.
This space is necessary for proper sealing.
Step 12: Remove Air Bubbles
Run a plastic spatula around the inside of each jar.
This releases trapped air bubbles.
Adjust the jam level if necessary.
Step 13: Seal the Jars
Wipe jar rims carefully with a clean damp cloth.
Place lids on jars.
Apply bands fingertip tight.
Do not overtighten.
Step 14: Water Bath Process
Place jars into boiling water.
Ensure water covers jars by at least 1 inch.
Process for:
- 10 minutes
Adjust processing time if you live at higher altitudes.
After processing:
- Turn off heat.
- Wait 5 minutes.
- Remove jars carefully.
Place them on a towel-lined surface.
Step 15: Cool and Check Seals
Allow jars to cool undisturbed for:
- 12 to 24 hours
You should hear the characteristic “pop” as jars seal.
After cooling:
Press the center of each lid.
A properly sealed lid will not move.
Any unsealed jars should be refrigerated.
