Ingredients
Scale
3 cups fresh or frozen strawberries, halved or quartered
2 cups fresh or frozen cranberries
4 cups granulated sugar
1/2 cup water
1 tablespoon lemon juice
1 teaspoon ground cinnamon
1/2 teaspoon ground allspice
Instructions
Prepare your canning station: sterilize half-pint (8 oz) jars, lids, and bands. Keep jars hot in a water bath canner.
Combine strawberries, cranberries, water, and lemon juice in a large, heavy-bottomed pot.
Bring the mixture to a boil over medium-high heat, stirring often. Reduce heat and simmer for 10 minutes, mashing the fruit slightly with a potato masher as it softens.
Stir in the granulated sugar, cinnamon, and allspice. Return the mixture to a full rolling boil that cannot be stirred down.
Boil hard, stirring constantly to prevent scorching, until the jam reaches 220 degrees Fahrenheit on a candy thermometer, or passes the plate test (a small amount dropped on a chilled plate wrinkles when pushed). This usually takes 15 to 25 minutes after adding sugar.
Remove the pot from the heat. Skim off any foam from the surface using a metal spoon.
Ladle the hot jam into the hot, sterilized jars, leaving 1/4 inch headspace.
Wipe the rims clean with a damp cloth. Center the lids and screw on the bands until fingertip tight.
Process the filled jars in a boiling water bath canner for 10 minutes, adjusting time for altitude if necessary.
Remove jars and let them cool undisturbed on a towel-lined counter for 12 to 24 hours until sealed. Check seals; store sealed jars in a cool, dark place.
Notes
For the plate test, chill a small plate in the freezer before starting. Drop a teaspoon of jam onto the cold plate and return it to the freezer for one minute. Push the jam with your finger; if it wrinkles, it is done.
This recipe yields about 5 to 6 half-pint jars of Christmas jam.
If you prefer a smoother jam, you can use an immersion blender briefly after cooking the fruit but before adding the sugar.
