How to cook a Christmas jam?

You cook Christmas jam by combining cranberries, strawberries, sugar, and spices in a slow cooker, then cooking on high for about 4 hours until thick and bubbling.

How do you make Christmas jam in a crockpot?

Just toss all ingredients into the crockpot, mix well, and cook on high. Stir halfway through, then blend lightly and jar the jam once it’s thick and glossy.

Is 4 hours on high the same as 8 hours on low in a slow cooker?

Generally, yes. Four hours on high equals about eight hours on low, though this jam works best on high for quicker thickening.

It’s a festive fruit preserve made from cranberries, strawberries, and holiday spices. It’s sweet, tangy, and filled with cozy seasonal flavors — like Christmas in a jar.

Instructions

1. Add frozen cranberries, strawberries, both sugars, allspice, cinnamon, and ginger to a slow cooker and mix well to coat the fruit evenly.

2. Cover and cook on high for 4 hours. Stir once halfway through to prevent sticking, then re-cover and let finish cooking until soft and bubbling.

3. Carefully transfer the hot mixture to a blender and pulse twice, just enough to break it down but not purée completely.

4. Spoon the hot jam into clean, sterilized jars. Wipe rims, secure lids loosely, and let jars cool completely at room temperature.

5. After cooling, tighten lids slightly and refrigerate overnight before use.

Notes

Avoid adding extra liquid, as the berries release plenty of moisture.

Don’t open the lid too often during cooking.

For thicker jam, crack the lid slightly during the final hour.

To check readiness, place a spoonful on a chilled plate—if it holds its shape, it’s done.
