What makes this sauce special is its versatility—use it as a glaze for roasted pork, a sandwich spread, or a topping for cheese boards. The celery adds a subtle crunch that cuts through the fruit's natural sweetness, while a touch of vinegar ensures proper acidity for safe canning.

Each jar will yield about ½ cup of sauce, perfect for gifting or stocking your pantry.

Safety is our top priority, so we'll cover proper jar preparation, processing times, and storage guidelines to ensure your sauce stays fresh for up to a year.

Whether you're a seasoned canner or trying it for the first time, this method delivers foolproof results every season. Let's get started on preserving that summer flavor.

Ingredients for apple plum sauce recipe canning

Six jars of summer flavor, ready to preserve that perfect sweet-tart balance.

Plums and apples are the stars here—ripe but firm is key. Hit up local farmers markets in summer for the best fruit, or grab organic from Whole Foods if you're shopping year-round. The celery adds that signature crunch, so don't skip it—Trader Joe's has great pre-washed bunches. For the jars, Kerr brandwater bath canner from Amazon—it's a one-time investment that pays off every season.

No pint jars? Half-pint jars work too, just double the processing time. Subbing apples? Pears work great, but keep the sugar at 1.5 cups—pears are sweeter. Vinegar is non-negotiable for safe canning (it's what preserves the color and texture), but apple cider vinegar adds a nicer flavor. Running low on ginger? Ground ginger at half the amount works in a pinch, but fresh is worth it. The sugar can be adjusted—if your fruit is extra tart, reduce to 1 cup. For the celery, frozen works in a jam if you're in a bind, but fresh is ideal.

This sauce keeps for up to a year in a cool, dark pantry—just make sure those jars are sealed tight. I always label mine with the date (a Sharpie on the lid works). Reheat gently in a saucepan or microwave for 20-30 seconds before using. The celery crunch softens slightly after canning, but it's still there—trust me. Freeze extras in ice cube trays if you don't want to can them all. And if you make more than you need? Gift them—this sauce is always a hit at holiday parties.

Step-by-step instructions for apple plum sauce canning

Here's how to preserve that perfect sweet-tart balance in your jars.

In a large pot, combine the 2.5 lb ripe plums, 2 medium apples, 1 medium onion, and 1 bunch celery stalks. You want the fruit roughly chopped—about ½-inch pieces—so it cooks evenly and breaks down nicely. Add 1 tbsp fresh ginger and 0.5 cup white vinegar to the pot.

Bring everything to a boil over medium-high heat, then reduce to a simmer. Let it cook uncovered for 20-25 minutes until the fruit softens and the mixture thickens slightly. You're looking for a consistency where the fruit releases its juices but still holds some texture—it should be easy to mash with a wooden spoon but not completely mushy.

Stir in the 1.5 cups granulated sugar, 1 tsp salt, and 0.5 tsp ground black pepper. Taste the mixture and adjust the sugar to your preference—you want a balance between sweet and tart, with just a hint of spice from the ginger and pepper. The sauce should coat the back of a spoon but still have some body to it.

Let the sauce simmer uncovered for another 15-20 minutes, stirring occasionally. This step ensures the flavors meld together and the sauce thickens further. You'll know it's ready when it reaches a consistency that's slightly thicker than applesauce but still pourable. If it's too thick, add a splash of water or vinegar to loosen it up.

While the sauce simmers, wash the 6 whole pint-Mason jars, lids, and bands in hot, soapy water, and rinse them thoroughly. Place the jars on a clean towel or rack to dry. You can also run them through a dishwasher cycle to sterilize them if you prefer. The key here is to ensure everything is spotless and free of any residue that could interfere with the sealing process.

Once the sauce is ready, carefully ladle it into the jars, filling them to within ½-inch of the top. Use a wooden spoon or spatula to remove any air bubbles trapped in the sauce. This step is crucial—air bubbles can cause the jars to fail to seal properly. Tap the jars gently on the counter to help release any lingering bubbles.

Place the filled jars on a rack in a large pot, ensuring they're covered by at least 1-2 inches of water. Bring the water to a gentle boil over medium heat. Once boiling, reduce the heat to maintain a steady simmer and process the jars for 15 minutes. This time ensures the sauce is safely preserved and the jars seal properly.

After processing, carefully remove the jars from the pot using tongs and place them on a clean towel. Let them cool undisturbed for 12-24 hours. You'll hear a satisfying "ping" as the lids seal. To check, press down on the center of each lid—if it doesn't pop back up, the jar is sealed. If any jars don't seal, store them in the refrigerator and use them within a week.

Once all the jars are sealed, label them with the date and store them in a cool, dark place. Properly canned apple plum sauce will keep for up to 1 year, though the flavor only gets better with time. When you're ready to use it, simply open a jar and enjoy the sweet-tart balance of the fruit, the subtle crunch from the celery, and the warm spices from the ginger and pepper.

This sauce is incredibly versatile—use it as a topping for yogurt or oatmeal, mix it into marinades, or spread it on toast with a sprinkle of cinnamon. The celery adds a unique crunch that sets this sauce apart from traditional fruit preserves, making it a standout addition to your pantry.

Dietary considerations for this apple plum sauce recipe canning

Gluten-Free Adaptation

This recipe is naturally gluten-free since it relies on fresh fruit, vegetables, and basic pantry staples like vinegar and sugar. The only potential concern is cross-contamination during canning—always use a clean workspace and dedicated tools if you're sharing equipment with gluten-containing products.

I've tested this sauce in my own gluten-free kitchen, and it holds up perfectly on gluten-free bread or as a marinade for grilled meats. 🌾

Low-Sugar Options

If you're watching sugar intake, reduce the granulated sugar to 1 cup and add 1 tbsp lemon juice to enhance natural sweetness while balancing acidity. I've also had success using ½ cup honey instead of sugar—it adds subtle floral notes that complement the fruit beautifully.

Remember, proper acidity is crucial for safe canning, so never skip the vinegar entirely. Test your sauce's pH with a kit if you're making significant sugar reductions.

Vegan-Friendly Swaps

This sauce is already vegan, but you can elevate it further by using maple syrup instead of granulated sugar for a richer flavor profile. For extra depth, add 1 tsp smoked paprika or ½ tsp cinnamon during the final simmer—both work beautifully with the fruit's natural sweetness.

I've made this version for vegan potlucks, and it's always a crowd-pleaser when served with roasted vegetables or as a glaze for tofu dishes.

Allergy Considerations

For nut allergies, this recipe is completely safe as written—just ensure all ingredients are processed in nut-free facilities. If celery is a concern, substitute with ½ cup finely diced fennel for a similar texture without cross-contamination risks.

Always check your vinegar brands for potential allergens, as some commercial varieties may be processed in shared facilities. I keep a separate canning kit for allergy-sensitive recipes in my kitchen to prevent any accidental exposure.

Diabetic-Friendly Adjustments

To make this sauce more diabetes-friendly, reduce sugar to ½ cup and add 1 tbsp chia seeds during the final simmer—they add fiber and help stabilize blood sugar. You can also increase the vinegar to ⅔ cup to enhance tartness while keeping carbs in check.

I've found this version works well when paired with high-protein meals like grilled chicken or fish, where the sauce serves as a flavorful complement rather than a carbohydrate focus. Always monitor portion sizes when using reduced-sugar versions.

Kid-Friendly Versions

For picky eaters, blend the sauce until smooth to eliminate any visible celery pieces, then serve it as a sweet dip with apple slices or crackers. I've had great success with this approach—kids love the familiar apple flavor without noticing the subtle crunch.

For extra appeal, add ½ tsp vanilla extract during the final simmer. The natural sweetness makes it perfect for lunches, and the canning process means you can prep it once and use it all month without worrying about spoilage. 🍎
