Key Ingredients for the Perfect Christmas Jam

Ingredient Breakdown
Cranberries: Bring a tangy, festive flavor and help the jam set naturally.
Strawberries: Add natural sweetness and smooth texture.
White sugar: Keeps the color vivid and enhances the fruit flavor.
Light brown sugar: Adds molasses notes for depth.
Allspice: Gives a round, holiday spice aroma.
Cinnamon: Adds cozy warmth and sweetness.
Ginger: Lifts everything with gentle heat and freshness.
Substitutions: Use maple syrup, coconut sugar, or erythritol for a lighter touch. Fresh ginger or a pinch of nutmeg and cloves can swap in for ground allspice.
How to Make Tasty Slow Cooker Christmas Jam
Step 1 – Combine the Ingredients
Place frozen cranberries and strawberries into your slow cooker. Add both sugars, allspice, cinnamon, and ginger. Stir until the fruit is coated evenly. Don’t add any water — the berries will release plenty of juice as they cook. This helps the jam thicken naturally without becoming runny.
Step 2 – Cook Slowly and Stir Occasionally
Cover and cook on high for 4 hours, stirring once halfway through to prevent sticking. Keep the lid closed as much as possible to trap steam and flavor. The mixture will bubble and soften as the fruit breaks down and the sugars caramelize slightly.
Step 3 – Blend to Desired Texture
Once soft and fragrant, carefully transfer the hot mixture for your Tasty Slow Cooker Christmas Jam to a blender. Pulse twice for a chunky, spreadable jam that looks as good as it tastes. Avoid pureeing completely — a little texture keeps it interesting. Always handle hot mixtures with care to avoid splatters.
Step 4 – Spoon Into Sterilized Jars
Using a ladle, spoon the hot jam into clean, sterilized jars. Leave a little headspace at the top. Wipe the rims clean and secure the lids loosely. If you’re unsure how to sterilize jars, simply boil them for 10 minutes or run them through a dishwasher cycle with heat dry.
Step 5 – Cool and Store
Let the jars cool completely at room temperature before tightening the lids fully. Then refrigerate overnight. The jam will thicken further as it chills, developing that perfect spoonable consistency.

Tips for the Best Homemade Christmas Jam
For a thicker Tasty Slow Cooker Christmas Jam, crack the lid slightly during the last hour of cooking. To test doneness, spoon a little onto a chilled plate if it holds its shape, it’s ready. Avoid opening the lid too often, as this releases heat and slows cooking. For a stronger spice flavor, increase the cinnamon slightly or add a pinch of nutmeg.
Substitutions and Flavor Variations
You can use fresh berries if you prefer a more vibrant fruit flavor. Swap maple syrup for some of the sugar for a deeper sweetness. Coconut sugar or dark brown sugar adds richness, while stevia or erythritol makes it lower in sugar. Replace allspice with equal parts cinnamon, nutmeg, and cloves for a classic holiday blend. Try adding orange zest for a citrusy twist.
How to Serve Your Christmas Jam
This jam pairs beautifully with biscuits, scones, or toast, but you can also spread it over pancakes, waffles, or cheesecake. It’s amazing on cheese boards, especially with brie or sharp cheddar. For something creative, swirl it into yogurt or spoon over vanilla ice cream for a festive dessert.
