Ingredients for apple plum sauce recipe canning
These vibrant fruits and precise measurements transform summer abundance into restaurant-quality preserves.
| Ingredient | Amount | Notes |
|---|---|---|
| Apples (Honeycrisp or Granny Smith) 🍎 | 4 cups | Peeled, cored, diced (½-inch pieces) |
| Plums (Ripened, firm varieties) 🍑 | 4 cups | Pitted, diced (¼-inch pieces) |
| Granulated Sugar 🍚 | 3 cups | White or light brown preferred |
| Lemon Juice (Freshly squeezed) 🍋 | ½ cup | For acidity balance (pH safety) |
| Water 💧 | 1 cup | For thinning if needed |
| Apple Cider Vinegar 🍶 | 2 tbsp | For preservation and tang |
| Ground Cinnamon 🌿 | 1 tsp | For depth (optional but recommended) |
| Salt 🧂 | ½ tsp | Kosher or sea salt preferred |
| Pectin (Low-Methoxyl or Pomona's Universal) 🧪 | 1 tbsp | For improved gelling (optional) |
| Ball or Kerr Mason Jars (8 oz) 🥫 | 6 jars | New, sterilized canning jars |
The fruit selection is everything—Honeycrisp apples add sweetness while Granny Smith brings tartness that balances the plums. Ball or Kerr jars are the gold standard for canning, but any new, food-grade jars will work if properly sterilized. For plums, look for firm, ripe varieties like Santa Rosa or Italian prunes—they hold up best during cooking. Apples should be crisp, not mealy. If you're short on time, pre-cut fruit from the produce section works, but fresh is always better. The key is uniform size—small dice ensures even cooking and texture.
No fresh lemon juice? Bottled lemon juice with no added water works in a pinch, but fresh is ideal for that bright acidity. Running low on pectin? Extra lemon juice or apple cider vinegar can help with gelling, though results may vary. Substituting brown sugar for white? Reduce by 1 tbsp to account for moisture differences. For a smoother texture, blend the cooked sauce briefly before canning—just don't overdo it, or you'll lose that beautiful fruit texture. The cinnamon is optional but worth the extra minute for warmth and depth.
Sterilize jars and lids in boiling water for 10 minutes before filling—this ensures a perfect seal. The sauce will thicken as it cools, so don't worry if it looks runny in the jars. Once sealed, store in a cool, dark pantry for up to 12 months. For gifting, wrap jars in kraft paper with a ribbon—Nana Mae's trick was to include a handwritten note about the harvest year. Reheat gently in a saucepan or microwave for 30 seconds before serving to restore that just-made-from-scratch quality.

Step-by-step instructions for preserving apple plum sauce
Transform your fruit harvest into vibrant preserves with this foolproof canning method.
Prepare and Sterilize Your Equipment
Begin by washing the 6 jars and their lids in hot, soapy water, then rinse thoroughly. Place the jars in a large pot and cover with water. Bring to a boil for 10 minutes to sterilize—this ensures a clean seal and prevents spoilage. Meanwhile, prepare a clean towel to dry the jars after sterilization.
While the jars sterilize, gather the remaining ingredients: 4 cups diced apples, 4 cups diced plums, 3 cups granulated sugar, and the rest of your dry ingredients. I like to measure everything out first so I don’t get distracted mid-process. Keep the pectin and lemon juice handy—they’re the secret to that perfect gel texture.
Combine Fruit and Sugar for Maximum Flavor
In a large, heavy-bottomed pot, combine the 4 cups apples and 4 cups plums with the 3 cups granulated sugar. Stir gently to distribute the sugar evenly, letting it dissolve into the fruit juices. Bring the mixture to a boil over medium-high heat, then reduce to a simmer for 10 minutes, stirring occasionally.
This step is where the magic happens—the sugar extracts the fruit’s natural pectin, and the gentle simmer softens the fruit while preserving its vibrant color. You’ll notice the mixture thicken slightly as it cooks. If you’re using tart apples like Granny Smith, this simmering helps balance their acidity for a smoother final product.
Add Acidifiers and Pectin for Preservation
Once the fruit mixture has simmered for 10 minutes, remove it from heat and stir in the 0.5 cup lemon juice, 2 tbsp apple cider vinegar, 1 tsp ground cinnamon, and 0.5 tsp salt. The acidity from the lemon juice and vinegar is critical—it lowers the pH, making the preserves safe for long-term storage. Return the pot to medium heat and bring it back to a full boil.
While the mixture heats, sprinkle the 1 tbsp pectin over the surface and stir vigorously for 1 minute to fully dissolve. This pectin boosts the natural gelling properties of the fruit, ensuring your sauce sets properly in the jars. Watch for a slight thickening—this is your cue that the pectin is working. If the mixture looks too thick, add the 1 cup water now to adjust consistency.
Fill and Seal Jars for Long-Term Storage
Using a ladle or funnel, carefully fill each of the 6 sterilized jars with the hot sauce, leaving ½-inch headspace at the top. Tap the jars gently on the counter to remove any air bubbles trapped in the sauce. Wipe the rims with a clean, damp cloth to ensure a perfect seal.
Place the lids on the jars and screw on the bands until fingertip-tight—don’t over-tighten, or the seals won’t form properly. Return the filled jars to the pot of boiling water, ensuring they’re fully submerged. Process in the boiling water bath for 15 minutes to kill any remaining bacteria and create a vacuum seal. This step is non-negotiable for shelf stability.
Cool, Store, and Enjoy Your Preserves
Remove the jars from the water bath and let them cool undisturbed for 12 hours. You’ll hear a satisfying ping as the lids seal—this confirms your preserves are properly canned and safe to store. Once cooled, check that the lids are concave and don’t flex when pressed. Any jars that don’t seal should be refrigerated and used within 1 week.
Store the sealed jars in a cool, dark place, like a pantry or cellar. Your apple plum sauce will keep for up to 12 months, making it the perfect year-round treat. The flavors will deepen over time, but the sauce should remain vibrant and delicious. Use it as a glaze for roasted meats, a topping for yogurt, or simply spread it on toast for a taste of summer anytime.
Pro Tips For Making Apple Plum Sauce Recipe Canning
- Peel Before Pitting: DESCRIPTION: Plums and apples are stubborn when it comes to peeling after pitting—trust me, I’ve tried. Cut them in half first, then peel while they’re still whole. The skin slides off like a glove, and you won’t end up with a mess of stuck-on flesh in your sauce. (Yes, even if you’re impatient like me.)
- Simmer Low and Slow: DESCRIPTION: Crank the heat to boil the fruit mixture first, but once it’s bubbling, drop it to a gentle simmer. After burning three batches, I finally figured out that a fast boil turns the sauce into mush—you want those plums and apples to break down, not dissolve. Thirty minutes at a low simmer does the trick.
- Strain Twice for Smoothness: DESCRIPTION: One pass through a fine-mesh strainer won’t cut it. After the first strain, press the pulp with a wooden spoon to extract every last drop of juice, then strain again. I learned this the hard way—my first batch had visible fruit bits that looked like someone forgot to blend. (Your future self will thank you.)
- Acid Test Before Canning: DESCRIPTION: Lemon juice isn’t just for flavor—it’s your safety net. Use a pH strip or add an extra tablespoon per quart if you’re unsure. I skipped this once and ended up with a jar that looked fine but tasted off. Better safe than sorry, especially when canning. (And yes, even if the recipe says “just add lemon juice.”)
Storing and reheating your leftovers
Refrigerator Storage
If you're not canning immediately, store your apple plum sauce in an airtight container in the refrigerator for up to 2 weeks. I like to use glass mason jars with tight-sealing lids—they keep the sauce fresh and make it easy to grab for quick meals.
The sauce will thicken slightly in the fridge, so give it a quick stir before reheating. This is perfect for meal prep when you want to use the sauce within a couple of weeks without canning. 💫
Freezer Preservation
For longer storage without canning, freeze the sauce in 1-cup portions using silicone molds or freezer-safe containers. Leave ½-inch headspace to prevent expansion cracks. Label with the date—it stays good for up to 6 months.
Thaw overnight in the fridge before using. I often freeze extra batches to use as a glaze for holiday roasts. The texture remains smooth, though slightly softer than canned versions. ❄️
Reheating Canned Sauce
Gently reheat canned sauce in a saucepan over low heat for 5-10 minutes, stirring occasionally, until warmed through. Avoid boiling to prevent skin formation. For microwave reheating, transfer to a microwave-safe bowl and heat in 30-second intervals, stirring between each, until warmed.
The sauce should reach 165°F for safety. I find reheating in small batches preserves the best texture. 🔥
Reviving Thickened Sauce
If your sauce thickens too much during storage, revive it by adding 1-2 tablespoons of water or fruit juice and reheating gently. For canned jars, simply open and stir in the extra liquid before reheating.
This works especially well if you've stored it for several months and want to restore that glossy consistency. A splash of fresh lemon juice can also brighten flavors that have settled. 💡
Shelf Life Indicators
Check sealed jars periodically for proper sealing—press the lid center with a finger. If it pops up, the jar didn't seal properly and should be refrigerated for 1 week use. Discard any jars with mold, off odors, or cloudy contents.
Properly sealed jars will last 12 months in a cool, dark pantry. I always date my jars with a marker to track freshness. When in doubt, trust your senses—if it doesn't look or smell right, don't risk it. 🧂
Gifting and Travel
For gifting, wrap sealed jars in kraft paper with a ribbon and include a handwritten note about the harvest year. The sauce makes a thoughtful, long-lasting gift that's perfect for holidays.
When traveling, pack jars upright in a cooler with ice packs—they'll stay safe for up to 24 hours this way. I've sent jars to friends across the country, and they always arrive in perfect condition. The key is keeping them upright to prevent leaks. 📦

Frequently asked questions
Can I use frozen apples and plums instead of fresh?
Fresh fruit is ideal for best texture, but you can use frozen fruit in a pinch! Thaw and drain excess liquid first, then pat dry with a paper towel. The sauce may be slightly softer, but the flavor will still be delicious. Just reduce the water by 2 tablespoons since frozen fruit releases moisture.
What's the difference between water bath and pressure canning?
This recipe uses water bath canning (safe for high-acid foods like fruit sauces) which requires 15 minutes of processing. Pressure canning is only needed for low-acid foods like meats or vegetables. The acidity from lemon juice and vinegar makes water bath perfect here—it's simpler and preserves all the vibrant fruit flavors.
How do I know if my jars sealed properly?
After cooling 12 hours, press the jar lid center with your finger. If it pops back (concave), it's sealed! If it springs back (convex), the seal failed. Unsealed jars should be refrigerated and used within 1 week. Store sealed jars in a cool, dark pantry—they'll keep for 12 months.
Can I adjust the sweetness level?
Yes! For less sweetness, reduce sugar by ½ cup (use 2½ cups total). For more tartness, add 1 extra tablespoon lemon juice. Remember: sugar helps preserve texture, so drastic reductions may make the sauce softer. Taste as you cook—you can always adjust before canning.
What are the best uses for this sauce?
This versatile sauce works as a glaze for roasted pork or chicken, a topping for pancakes, or a dip for fresh bread. Try it in stir-fries, as a marinade base, or even mixed into yogurt. The balance of sweet-tart makes it perfect for both sweet and savory dishes—Nana Mae used to call it "the kitchen's Swiss Army knife!"
