"Bright cranberry tang with warm spice makes this my go-to holiday gift jam. So easy to make, and everyone asks for a jar."
Benefits at a glance:

- Great for gifting, spreading, and spooning over desserts.
The cooking process explained
You’ll start by adding fruit, sugars, and spices to the slow cooker, cook until everything breaks down and gets syrupy, then lightly blend for a jam-like texture. The whole process is very forgiving: four hours on high with one halfway stir gives tender fruit and concentrated flavor. After blending, ladle hot jam into clean jars, cool, and chill overnight so textures firm up.

What you’ll need
- 1 1/2 pounds cranberries, fresh or frozen
- 1 1/2 pounds strawberries, fresh or frozen
- 1 cup granulated sugar
- 1 1/4 cups light brown sugar
- 2 teaspoons ground allspice
- 1 teaspoon ground cinnamon
- 1/2 teaspoon ground ginger
- Optional: zest of one orange or 1 tablespoon lemon juice
Substitutions and clarifications:
- Cranberries: frozen are fine and save a step; no need to thaw.
- Strawberries: frozen work well; if using large fresh berries, quarter them.
- Sugars: swap brown sugar for coconut sugar for a deeper flavor, but texture and color will change.
- Citrus: orange zest brightens the jam, lemon juice increases acidity and shelf life slightly.
Step-by-step instructions
- Add cranberries, strawberries, both sugars, and spices to the crockpot. Stir to combine.
- Make sure the sugars are distributed so they dissolve evenly as the fruit heats. If using zest, add it now; add lemon juice after cooking if you prefer a fresher citrus note.
- Cover and cook on high for four hours, stirring once halfway through.
- Stirring helps prevent hot spots and keeps the fruit from sticking around the edge. If your slow cooker runs hot, check at 3 hours.
- Blend the hot mixture with an immersion blender or in batches with a countertop blender. Pulse just two to three times for a jam-like texture.
- Do not over-blend if you want visible fruit pieces. When using a countertop blender, vent the lid slightly and cover with a towel to avoid pressure build-up from the hot jam.
- Ladle hot jam into clean jars. Wipe rims and secure lids lightly.
- Use heatproof jars and a ladle to avoid spills. Tighten lids just until seated; they will seal as the jam cools.
- Cool at room temperature, then refrigerate overnight before using.
- Chilling overnight helps the jam thicken and the flavors to meld.
Serving suggestions
- Spread on warm biscuits, toast, or cornbread for a bright holiday breakfast.
- Spoon over vanilla ice cream or cheesecake for a festive topping.
- Use as a glaze for baked ham or roasted pork; mix with a little mustard or bourbon for a savory-sweet finish.
- Offer on a cheese board with sharp cheddar, brie, or goat cheese and crackers.
- Package in pretty jars with a ribbon for neighbor or teacher gifts.
Storage and reheating tips
- Refrigerator: store jam in a sealed container for up to 3 weeks. Label jars with date.
- Freezer: freeze in airtight containers for up to 6 months; leave headspace for expansion. Thaw overnight in the refrigerator.
- Reheating: warm gently on the stovetop over low heat to loosen frozen or very firm jam. Stir frequently.
- Canning for shelf stability: this recipe was written for refrigerated storage. If you want shelf-stable jars, consult tested water-bath canning guidelines from trusted sources before processing.
Helpful cooking tips
- Use frozen fruit straight from the bag to skip thawing; cooking time is the same.
- Taste before jarring and adjust sweetness or acidity with a little more sugar or lemon juice.
- Pulse blending keeps a rustic texture; blend longer for a smoother spread.
- Sterilize jars in hot, soapy water and keep them warm until filling to reduce breakage when adding hot jam.
- If jam looks too loose after chilling, return to low heat and simmer uncovered 10-15 minutes, then cool and chill again.
Flavor swaps
- Orange-cranberry twist: add the zest of one orange and 1/4 cup orange juice.
- Spiced pear-berry: replace half the strawberries with diced pears and add a pinch of nutmeg.
- Bourbon berry: stir in 1 tablespoon of bourbon after cooking for adult-friendly warmth.
- Less sweet: reduce granulated sugar to 3/4 cup and brown sugar to 1 cup, then taste and adjust.
