Ingredients

16 ounces (450 g) fresh or frozen strawberries, hulled and finely diced (if using frozen, thaw completely and include any accumulated juices)
12 ounces (340 g) fresh or frozen cranberries, rinsed and picked over to remove any soft or bruised berries
1/2 cup (120 ml) freshly squeezed orange juice (from about 2 medium navel oranges)
1 tablespoon freshly grated orange zest (packed, avoiding the bitter white pith)

3 cups (600 g) granulated white sugar (essential for proper preservation, texture, and sheen)
1 package (1.75 oz / 49 g) powdered fruit pectin (regular, not low-sugar)
1/2 teaspoon unsalted butter (optional, stirred in during boiling to dramatically reduce surface foam)

1 teaspoon ground Ceylon cinnamon (or 2 whole cinnamon sticks, removed before jarring)
1/4 teaspoon ground cloves
1/4 teaspoon freshly grated nutmeg
1/8 teaspoon ground allspice
Pinch of fine sea salt (balances sweetness and amplifies the berry notes)

Large, heavy-bottomed 6-to-8-quart stainless steel or enameled Dutch oven (a wide base helps moisture evaporate faster and prevents boil-overs)
Potato masher or sturdy wooden spoon
Digital instant-read thermometer or candy thermometer (optional, for checking the $220^\circ\text{F} / 104^\circ\text{C}$ gel point)
4 clean half-pint (8-ounce) glass mason jars with new two-piece lids and bands
Wide-mouth canning funnel and ladle

Sanitize your jars: Wash your glass jars, lids, and bands in hot, soapy water. Rinse thoroughly and keep the jars warm (either in a $200^\circ\text{F} / 95^\circ\text{C}$ oven or submerged in simmering water) until ready to fill so the glass does not crack when hot jam is ladled inside.
Prepare the fruit: Hull and finely chop the strawberries into 1/4-inch pieces so they distribute evenly throughout the spread. Leave the cranberries whole—they will pop naturally as they heat, releasing their natural pectin.
Combine in the pot: Add the diced strawberries, whole cranberries, freshly squeezed orange juice, orange zest, ground cinnamon, cloves, nutmeg, allspice, and sea salt to your heavy-bottomed pot. Stir well to coat the berries in the citrus and spices.

Warm the fruit: Place the pot over medium-low heat. Cover with a lid and let the mixture warm gently for about 8 to 10 minutes, stirring occasionally with a wooden spoon.
Release juices and mash: As the heat rises, the cranberries will begin to pop and burst. Once the fruit has softened and released a generous amount of ruby liquid, remove the lid and use a potato masher to gently crush the berries to your desired consistency—leaving a few small chunks gives the jam an artisanal, homemade texture.

Whisk in the pectin: Sprinkle the powdered fruit pectin evenly over the warm fruit mixture, stirring constantly so no clumps form. Add the 1/2 teaspoon of butter if using.
Bring to a full boil: Increase the stove burner to high heat. Stirring continuously to prevent scorching, bring the mixture to a full, rolling boil—a vigorous boil that cannot be stirred down even while actively moving your spoon through the center of the pot.
Add the sugar: Pour in all 3 cups of granulated sugar at once. Stir rapidly until the sugar completely dissolves and the mixture turns glossy and deep crimson.

Hard boil for the set: Return the mixture to a hard, full rolling boil over high heat. Boil vigorously for exactly 1 to 2 minutes, stirring constantly from the bottom of the pot. Do not walk away during this stage, as jam can bubble up quickly.
Test for doneness: Turn the heat down to low or remove the pot from the burner completely. You can verify the jam has reached its setting point using two methods:
- The Cold Plate Test: Spoon a teaspoon of hot jam onto a plate that has been chilling in the freezer for 10 minutes. Return the plate to the freezer for 1 minute, then push the edge of the jam with your finger. If the surface wrinkles and holds a clean path when parted, it is ready.
- Temperature Check: A digital thermometer inserted into the center of the jam should read $220^\circ\text{F} ( $104^\circ\text{C}$ ) at sea level.
Skim any foam: If any light pink foam remains on the surface, gently skim it off with a metal spoon for crystal-clear, jewel-like jars.

Fill the jars: Place a wide-mouth funnel over your warm, clean jars and ladle the hot Christmas Jam inside, leaving 1/4 inch of headspace at the top.
Seal and cool: Wipe the jar rims clean with a damp paper towel to remove any sticky residue, place the flat lids on top, and screw on the metal bands until fingertip-tight.
Let it set undisturbed: Allow the jars to cool completely at room temperature on a kitchen towel for 12 to 24 hours before moving or tilting them. As the jam cools, the pectin bonds tighten into a rich, spreadable gel.
Storage options:
- Refrigerator Storage: Once cooled, store jars directly in the refrigerator for up to 3 months.
- Freezer Storage: Leave 1/2 inch of headspace if freezing; store in freezer-safe jars for up to 1 year. Thaw overnight in the fridge before serving.
- Water-Bath Canning (Shelf-Stable): Process filled jars in a boiling water bath canner for 10 minutes (adjusting for altitude) to store unopened in a cool, dark pantry for up to 12 months.

Holiday Charcuterie Boards: Serve in a small ceramic ramekin alongside baked brie, sharp white cheddar, prosciutto, toasted pecans, and crisp water crackers.
Festive Thumbprint Cookies: Spoon a half-teaspoon of jam into the center of almond shortbread thumbprint cookies before baking.
Savory Glaze: Whisk 3 tablespoons of Christmas Jam with 1 tablespoon of Dijon mustard and a splash of balsamic vinegar to glaze roasted pork tenderloin, turkey, or baked meatballs.
Spiced Apple-Cranberry Variation: Swap out 8 ounces of the strawberries for finely diced Honeycrisp or Granny Smith apples for an earthier, orchard-inspired holiday preserve.
