Apple Pie Filling for Canning
- Prep Time: 2 hours (including apple peeling and slicing)
- Cook Time: 20-25 minutes (filling preparation) + 20-25 minutes (water bath processing)
- Yield: Approximately 7 quarts or 14 pints
Ingredients
- 12 pounds firm, tart apples (such as Granny Smith, Honeycrisp, or a mix)
- 7 cups granulated sugar
- 2 cups Clearjel (NOT instant Clearjel, cornstarch, or flour)
- 1 teaspoon ground cinnamon
- ½ teaspoon ground nutmeg
- ¼ teaspoon ground cloves (optional)
- 2 ½ cups cold water
- 3 cups apple juice or cider
- 1 cup bottled lemon juice
Instructions
- Wash and sterilize your canning jars and lids. Keep jars hot in a water bath canner or large pot of hot water until ready to fill.
- Peel, core, and slice apples into uniform ½-inch thick pieces. To prevent browning, place sliced apples in a large bowl of water with 1 tablespoon of lemon juice per quart of water.
- In a very large stockpot, combine sugar, Clearjel, cinnamon, nutmeg, and cloves. Whisk thoroughly to eliminate lumps.
- Gradually add cold water, apple juice, and bottled lemon juice to the dry mixture, whisking constantly until smooth.
- Heat the mixture over medium-high heat, stirring constantly, until it thickens and begins to boil. Boil for 1 minute, continuing to stir. The mixture will become very thick.
- Drain the apple slices thoroughly. Gently fold the drained apple slices into the hot syrup. The mixture will be very thick and challenging to stir. Work quickly to coat all apple slices evenly.
- Return the filling to a gentle boil, stirring occasionally to prevent scorching. Cook for 3-5 minutes, or until the apples are heated through but still firm. Do not overcook; the apples should not be soft.
- Carefully ladle the hot apple pie filling into the hot, sterilized canning jars, leaving 1-inch headspace. Use a non-metallic spatula or chopstick to remove any air bubbles.
- Wipe jar rims clean with a damp cloth. Center new, warm lids on jars and apply screw bands until fingertip tight.
- Place filled jars into the hot water bath canner, ensuring they are fully submerged by at least 1 inch of water.
- Bring the water to a rolling boil. Process quart jars for 25 minutes or pint jars for 20 minutes. Adjust processing time for altitude (refer to altitude chart below).
- Turn off heat, remove canner lid, and allow jars to sit in the hot water for 5 minutes before carefully removing them with a jar lifter.
- Place hot jars on a wire rack or towel-lined surface, ensuring they are not touching, and allow them to cool undisturbed for 12-24 hours.
- Check seals: Lids should be concave and not flex when pressed. Remove screw bands, wipe jars, label, and store in a cool, dark place.
Essential Equipment for Safe Canning
Successful canning relies on having the right tools to ensure safety and preserve quality. Each piece of equipment plays a specific role in creating a sterile environment and achieving a proper seal.
Water Bath Canner & Jars
A water bath canner is a large pot with a lid and a rack, designed to fully submerge canning jars in boiling water. This method is suitable for high-acid foods like apple pie filling. Canning jars, made of tempered glass, are specifically designed to withstand the high temperatures of processing and create a vacuum seal. Always use new lids for each canning session, as the sealing compound is designed for a single use.
Basic Canning Tools
A jar lifter is essential for safely placing hot jars into and removing them from the canner, preventing burns. A canning funnel helps guide the filling into jars cleanly, keeping rims free of food particles that could interfere with sealing. A head space tool, often integrated with a bubble remover, ensures you leave the precise amount of space between the food and the lid, which is critical for proper sealing. Magnetic lid wands assist in safely handling hot lids from simmering water.
Choosing the Right Apples for Pie Filling
The success of your apple pie filling starts with selecting the correct apple varieties. Their texture and flavor profile are key to a delicious, stable product.
Best Apple Varieties
Firm, tart apples hold their shape well during canning and processing, preventing a mushy texture. Varieties like Granny Smith, Honeycrisp, Braeburn, and Fuji are excellent choices. A blend of tart and slightly sweet apples can create a more complex flavor. Avoid soft, mealy apples as they will break down excessively during the cooking and canning process.
Apple Preparation
Uniform apple slices are important for even cooking and a pleasing texture in the finished product. Aim for ½-inch thick slices. Peeling and coring can be time-consuming; a good apple peeler/corer can significantly speed up this step. To prevent browning while you prepare a large batch, submerge sliced apples in a solution of water and a small amount of lemon juice or a commercial anti-darkening product.
| Apple Variety | Texture After Canning | Flavor Profile |
|---|---|---|
| Granny Smith | Very Firm | Tart, Crisp |
| Honeycrisp | Firm | Sweet-Tart, Juicy |
| Braeburn | Firm | Sweet-Tart, Aromatic |
| Fuji | Moderately Firm | Sweet, Crisp |
| Golden Delicious | Softer | Sweet, Mild |
Understanding Clearjel: The Key Thickener
Clearjel is a modified corn starch specifically designed for canning. It provides excellent thickening properties, remains stable under high heat and acidic conditions, and prevents separation or weeping in canned foods. This stability is crucial for ensuring a safe, high-quality product that retains its desired consistency.
Standard cornstarch or flour are not suitable for canning apple pie filling. They break down during the long processing times, resulting in a thin, watery product. This breakdown can also create dense pockets that prevent proper heat penetration, posing a food safety risk. Clearjel maintains its thickening power and clarity, making it the only recommended thickener for home-canned pie fillings.
How To Can Apple Pie Filling: A Step-by-Step Guide for Success
Following a precise sequence of steps ensures your apple pie filling is not only delicious but also safe for long-term storage. Precision in measurements and technique is paramount.
Preparing Your Jars & Lids
Begin by washing jars, lids, and bands in hot, soapy water. Sterilize jars by submerging them in boiling water for at least 10 minutes, or by running them through a dishwasher’s sterilize cycle. Keep jars hot until ready to fill to prevent thermal shock when adding hot filling. Simmer new lids in hot (not boiling) water to soften the sealing compound, ensuring a proper seal.
Making the Syrup & Filling
The syrup base is where the flavor and thickening power come together. Whisk Clearjel thoroughly with dry ingredients before adding liquids to prevent lumps. Cook this mixture until it thickens and boils, ensuring the Clearjel is fully activated. Gently fold in the drained apple slices, coating them evenly. Heat the apples through in the syrup just until they are hot, but still firm, to avoid overcooking before processing.
Processing the Jars
Ladle the hot filling into hot jars, leaving exactly 1-inch headspace. This space is necessary for the vacuum seal to form. Remove air bubbles by running a non-metallic utensil along the inside of the jar. Wipe rims meticulously clean; any food residue can prevent a seal. Place lids and screw bands, tightening them “fingertip tight”—just enough resistance without overtightening. Place jars in the canner, ensuring they are covered by at least 1 inch of boiling water. The National Center for Home Food Preservation states that processing times for apple pie filling vary by altitude and jar size, with quart jars requiring 25 minutes at sea level. You can find detailed, research-backed guidelines at the NCHFP website.
| Altitude (Feet) | Pint Jars (Minutes) | Quart Jars (Minutes) |
|---|---|---|
| 0 – 1,000 | 20 | 25 |
| 1,001 – 3,000 | 25 | 30 |
| 3,001 – 6,000 | 30 | 35 |
| Above 6,000 | 35 | 40 |
Post-Canning Care and Storage
Proper post-processing care ensures a strong seal and extends the shelf life of your canned goods. Patience during this stage is key to success.
Checking the Seals
After processing, remove jars from the canner and place them on a towel-lined surface, spaced apart, to cool undisturbed for 12-24 hours. Do not retighten screw bands during this cooling period. Once completely cool, check each jar’s seal. A properly sealed lid will be concave (curved inward) and will not flex when pressed in the center. If a lid does not seal, refrigerate the contents and use within a few days, or reprocess with a new lid within 24 hours if the product has not been refrigerated.
Proper Storage Conditions
Once jars are sealed and cooled, remove the screw bands. The bands can trap moisture, potentially leading to rust and lid corrosion. Wash and dry the jars, then label them with the contents and date. Store canned apple pie filling in a cool, dark, dry place, such as a pantry or basement. Avoid storing above 95°F or below 32°F. Properly canned apple pie filling maintains its quality for up to 1 year. The USDA recommends consuming home-canned foods within one year for optimal quality.
Troubleshooting Common Canning Issues
Even experienced canners encounter challenges. Understanding common issues helps in addressing them effectively and safely.
Unsealed Jars
An unsealed jar means the vacuum seal did not form. This can happen due to food particles on the rim, improper headspace, overtightened bands, or a faulty lid. If a jar does not seal after cooling for 12-24 hours, you have two options: either refrigerate the contents and consume within a few days, or reprocess the jar. To reprocess, reheat the filling, transfer it to a clean, hot jar with a new lid, and process again for the full recommended time. This must be done within 24 hours of the initial processing.
Siphoning (Loss of Liquid)
Siphoning, or the loss of liquid from jars during processing, is a common issue. It can be caused by packing jars too tightly, inadequate headspace, fluctuating canner temperature, or rapid cooling after processing. While siphoning can look concerning, if the jar is properly sealed, the contents are safe to eat. However, the exposed food above the liquid may discolor or dry out. To minimize siphoning, ensure correct headspace, maintain a steady boil in the canner, and allow jars to cool for 5 minutes in the canner after processing before removing them.
