Christmas jam is a strawberry-cranberry preserve cooked with orange and warm spices, then water-bath canned so the jars keep on a pantry shelf. The fruit is high-acid, which is why a boiling-water canner is the right method. What most people need is one reliable batch size, the correct pectin order, and processing times that change with altitude.
Christmas jam is a deep-red strawberry and cranberry preserve scented with orange zest, cinnamon, and clove. It is built for water-bath canning: both fruits are high-acid, the sugar and pectin help it set, and a short boil in the canner gives the jars a vacuum seal for pantry storage.
The search usually hides two separate jobs. One is making a jam that actually sets. The other is processing it so it is safe to keep unrefrigerated. Skipping the water bath, reducing the sugar in a standard pectin recipe, or swapping liquid pectin for powdered pectin is how batches fail.
This recipe is a home-canning formula in the common Christmas-jam style, not a single USDA-named product. Safety depends on keeping the fruit high-acid, matching the pectin type to the method, using new two-piece lids, and processing half-pint or pint jars in a boiling-water canner with the time adjusted for your elevation.
What Christmas Jam Is, and What It Is Not
Most versions use more strawberries than cranberries. Strawberries supply color and sweetness. Cranberries add tartness and a large amount of natural pectin, which is why the jam sets more reliably than plain strawberry jam. Orange zest keeps the flavor bright. Cinnamon, ginger, clove, allspice, or nutmeg give it the holiday profile.
It is still jam, not cranberry sauce. A good batch should mound on a spoon and spread on toast without running like syrup. It should taste tart-sweet, not like mulled wine concentrate. A little spice goes a long way; too much clove makes the jars taste medicinal.
Christmas jam is also not a low-acid food. You do not pressure-can it. You also should not “can” it in reused metal food cans, seal it with paraffin, or invert hot jars and call that processing. Those methods are outdated and do not give the same protection as a boiling-water bath.
Choose the Method Before You Shop
Two safe approaches exist. Pick one and stay with it.
| Method | Best when | What you gain | What you give up |
|---|---|---|---|
| Liquid pectin | You want a predictable set and a larger yield | Short cook time, bright fruit flavor, easier first batch | You must use the full sugar amount the pectin requires |
| No added pectin | You have cranberries plus apple or orange and a thermometer | Less processed ingredients, slightly deeper cooked flavor | Longer cooking, more evaporation, smaller yield |
| Pomona’s or low-sugar pectin | You want less sugar | A set that does not depend on a high sugar load | You must follow that brand’s calcium and pectin steps exactly |
Do not mix these systems. Liquid pectin is added after the fruit and sugar have already boiled. Powdered classic pectin goes in before the sugar. Low-sugar pectin is a different product. Swapping one for another is a common reason Christmas jam stays pourable.
If the jars are gifts and you want them on a pantry shelf, can them. If you only need a few cups for this week, skip the canner and refrigerate the finished jam for about 2 to 3 weeks, or freeze it in freezer-safe containers with headspace.
What You Need
Ingredients for about 6 to 7 half-pint jars
This is a practical home batch, not the 10-jar gift marathon some recipes produce.
- 1½ pounds strawberries, fresh or frozen (about 6 cups prepared)
- ½ pound cranberries, fresh or frozen (about 2 cups)
- 5 cups granulated sugar
- 2 teaspoons ground cinnamon
- 1 teaspoon ground ginger
- ¼ teaspoon ground cloves
- ¼ teaspoon ground allspice or nutmeg
- 2 pouches liquid fruit pectin (3 ounces / 85 g each)
- Optional: 1 to 2 tablespoons finely grated orange zest
- Optional: ½ teaspoon butter or margarine, only to reduce foam
Frozen fruit works well here and is often the better winter choice. Thaw it first if you plan to chop it in a food processor. Do not drain the juice; that liquid is part of the measured fruit.
Use granulated white sugar with standard liquid pectin. Honey, brown sugar, or a reduced amount of white sugar will change both set and safety of the formula. If you want less sugar, use a pectin made for that purpose and follow its recipe, not this one.
Equipment
- 6- to 8-quart wide pot or Dutch oven
- Water-bath canner or a deep stockpot with a rack
- 7 half-pint (8-ounce) canning jars, plus a spare
- New two-piece lids
- Jar lifter, funnel, ladle
- Clean damp cloth for rims
- Timer
- Instant-read thermometer, helpful but not required for the pectin version
Half-pint jars are the right size for gifting and for a firm set. Pint jars are acceptable for most jam processes. Quart jars are a poor choice; the gel is often weaker and heat penetration is harder to keep consistent.
Make the Jam
- Wash the jars in hot soapy water. Keep them hot in the canner or in simmering water so they do not crack when filled. Wash the lids according to the manufacturer’s current directions. Modern lids usually do not need a hard boil.
- Prepare the fruit. Hull strawberries. Pick over cranberries and discard soft or shriveled ones. Pulse the fruit in a food processor until it is finely chopped, not a baby-food puree. A few small pieces look better in the jar than a perfectly smooth gel.
- Combine the fruit, sugar, spices, and orange zest in the pot. Stir over medium-high heat until the sugar dissolves. This matters. Undissolved sugar can leave grit and weaken the gel.
- Bring the mixture to a full rolling boil: bubbles that keep rolling across the surface even while you stir. Boil hard for 1 minute, stirring constantly so the jam does not scorch.
- Remove the pot from the heat. Stir in both pouches of liquid pectin. Return the pot to high heat and bring it back to a full rolling boil. Boil hard for 1 minute, stirring the whole time.
- Take the pot off the heat. Let it sit 2 to 5 minutes. Skim foam. The jam will look thinner than finished jam. That is normal. Pectin sets as it cools, not the moment it leaves the stove.
If you want a no-pectin batch instead, use a cranberry-heavy mixture and cook it to the gel point rather than following the two 1-minute boils above. At sea level, that is about 220°F (104°C). Drop the target by roughly 1°F for every 500 feet of elevation. A chilled-plate test works too: a spoonful on a frozen plate should wrinkle when you push it.
Can the Jars
Work while the jam is hot.
- Ladle jam into hot jars, leaving ¼ inch headspace.
- Remove air bubbles with a clean spatula or bubble tool. Recheck headspace.
- Wipe the rims with a clean damp cloth. Any sugar on the rim can prevent a seal.
- Apply lids and screw bands fingertip tight. Over-tightening can buckle lids and block air from escaping during processing.
- Lower jars into the canner. Water must cover the lids by 1 to 2 inches.
- Cover the canner. Bring the water to a full rolling boil, then start the timer.
Processing time
Many current Ball-style pectin jams use 10 minutes at low elevation. USDA tables for some cooked jams and jellies list 5 minutes at 0 to 1,000 feet, then more time as elevation rises. If you are following a specific tested source, use that source’s table. For this style of holiday jam in half-pint or pint jars, a conservative home-canning schedule is:
| Elevation | Process time after water returns to a boil |
|---|---|
| 0 to 1,000 feet | 10 minutes |
| 1,001 to 6,000 feet | 15 minutes |
| Above 6,000 feet | 20 minutes |
The timer starts only when the water is boiling again with the jars in it. If the boil dies, bring it back and restart the time.
When the time is up, turn off the heat. Remove the canner lid. Let the jars stand in the water for 5 minutes. Lift them straight up onto a towel. Do not tilt them. Leave them undisturbed for 12 to 24 hours.
How to Know the Jars Are Safe to Store
After the jars are fully cool:
- Press the center of each lid. It should be concave and should not flex.
- Remove the bands and lift the jar by the lid. A sealed lid stays put.
- Look for leaks, cracks, or dried jam on the rim.
Sealed jars keep best in a cool, dark cupboard. Peak quality is generally 12 to 18 months. The band can come off for storage; leaving bands on can hide a broken seal and rust the threads.
Unsealed jars go in the refrigerator and should be eaten within a few weeks. You can also reprocess an unsealed jar within 24 hours: empty it if needed to check the rim, use a new lid, and process for the full time again. Texture may soften slightly.
A sealed lid is not proof that an unsafe recipe became safe. It only means new air is staying out. Mold, bubbling, spurting liquid, or an off smell means the jar should be discarded. Do not taste suspect jam to “check.”
Why This Combination Sets When Plain Strawberry Jam Sometimes Does Not
Pectin needs acid, sugar, and heat to form a gel. Cranberries are naturally high in both pectin and acid. Strawberries are lower in pectin, especially when fully ripe or frozen and very soft. That is why the cranberry portion is doing structural work, not just adding Christmas flavor.
Standard liquid pectin still needs the listed sugar. Sugar is not only for sweetness. It binds water so pectin can form a network. Cutting 5 cups down to 3 cups in this formula is how you get cranberry syrup.
Batch size matters too. Doubling the pot looks efficient and often fails. A double batch heats unevenly, takes longer to reach a true rolling boil, and can overcook the pectin before the center of the pot is ready. Make two single batches instead.
Mistakes That Ruin Christmas Jam
Using the wrong pectin order. Liquid pectin last. Classic powdered pectin first. If the package and the recipe disagree, follow the pectin package for that product.
Calling a simmer a rolling boil. A lazy bubble around the edge is not enough. The boil has to keep moving while you stir.
Skipping the water bath because the lids popped. Open-kettle canning and jar inversion are no longer recommended. The process is what reduces yeasts, molds, and surface contamination.
Underfilling the canner. Water sitting at the shoulder of the jar is not a water bath. The lids need to be underwater.
Reducing sugar “to make it healthier” in a regular pectin recipe. Use a low-sugar pectin system if that is the goal.
Adding extra fruit “for more flavor.” Extra fruit changes the ratio. The batch may taste fine and still refuse to set.
Over-spicing. Start with the amounts above. You can stir a pinch more cinnamon into a refrigerated test jar later. You cannot pull clove back out of 7 sealed jars.
Disturbing hot jars. Sliding them, tightening bands, or putting them in a draft can break seals and cause siphoning.
How to Use Christmas Jam
The tart-sweet profile is why this jam earns a place beside more than toast.
- Spoon it over a block of cream cheese or baked Brie.
- Pair it with sharp cheddar, goat cheese, or aged gouda on a board.
- Use it as a glaze for ham, pork tenderloin, or roasted turkey in the last minutes of cooking.
- Spread it on turkey sandwiches instead of cranberry sauce.
- Fill thumbprint cookies or sandwich it in biscuits.
- Warm a spoonful into oatmeal, yogurt, or vanilla ice cream.
For gifts, half-pints are easier to finish. Add a “refrigerate after opening” note and the date. Opened jam belongs in the refrigerator and is best within a few weeks.
Refrigerator and Freezer Option
If you do not want to can, cook the jam through the pectin steps, cool it, and pack it into clean containers. Leave headspace if freezing. Refrigerator jam is a good way to test spice level before you commit to a full canner load. It is not shelf-stable.
Frequently Asked Questions
Can I use only cranberries? Yes, but the flavor will be much tarter and closer to cranberry spread. You would be making a different jam. Keep a tested cranberry jam or sauce formula if you drop the strawberries.
Can I use apples or pears instead of strawberries? That is a different holiday jam, closer to the cranberry-apple or cranberry-pear preserves in tested cookbooks. It can work well because apples and pears also bring pectin. Do not casually swap fruits in a pectin recipe and keep the same sugar and process unless the new formula is also written as a jam recipe.
Do I have to use orange zest? No. The jam will still be strawberry-cranberry spice jam. Zest adds aroma without much extra liquid. Orange juice in large amounts adds water and can soften the set.
Why is my finished jam loose? Common causes are a weak boil, old pectin, a doubled batch, extra fruit, or reduced sugar. Soft jam that was processed correctly is still safe if the jar sealed and shows no spoilage. Use it as a pancake sauce or meat glaze, or remake it using the remake directions for the pectin type you used.
Why is there foam or fruit floating at the top? Foam is trapped air. A little butter in the pot can reduce it; skimming helps the jars look cleaner. Floating fruit is common with chopped strawberries. Chopping more finely and letting the pot rest a few minutes before filling can help, but some separation is cosmetic.
Can I make this in a slow cooker, Instant Pot, or oven? Those are not approved substitutes for a boiling-water canner. Cook the jam on the stove. Process the filled jars in a water-bath canner or a tested atmospheric steam canner used according to its directions for jam.
How long does sealed Christmas jam last? Use sealed jars within a year for best color and flavor. Discard any jar with a broken seal, mold, fizzing, or an off odor.
Christmas jam is worth the pot of boiling water because the jars are actually useful: breakfast, cheese boards, and gifts from the same batch. Measure the fruit, respect the pectin, cover the jars with boiling water, and leave them alone while they cool. That is the difference between a pretty holiday project and jam you can trust on the shelf.
