Apple butter, with its rich, caramelized flavor and velvety texture, is a beloved spread that evokes feelings of warmth and home. Making your own apple butter is a rewarding experience, allowing you to control the ingredients and customize the flavor to your liking. But the question remains: can you safely can apple butter to enjoy its deliciousness year-round? The answer is a resounding yes, but it’s crucial to follow specific guidelines to ensure a safe and shelf-stable product. This comprehensive guide will walk you through the process, providing all the information you need to confidently and safely can apple butter at home.
Understanding the Science of Safe Canning
Safe canning relies on understanding the principles of food preservation. Microorganisms, such as bacteria, yeasts, and molds, are responsible for food spoilage. These organisms thrive in environments with moisture, warmth, and nutrients – conditions often found in home-canned goods.
The primary goal of canning is to eliminate these harmful microorganisms and create a vacuum seal that prevents their re-entry. This is achieved through heat processing, which involves subjecting filled jars to high temperatures for a specific duration.
Low-acid foods, like many vegetables and meats, require processing at 240°F (116°C) to kill Clostridium botulinum spores, which can produce a deadly toxin that causes botulism. This high temperature is only attainable through pressure canning.
High-acid foods, such as fruits, jams, jellies, and pickles, can be safely processed in a boiling water bath canner because the acidity inhibits the growth of Clostridium botulinum. Apple butter falls into this category, but the acidity level is still crucial.
The Importance of Acidity in Apple Butter Canning
Apple butter’s safety depends on its acidity. The lower the pH (higher the acidity), the less likely it is for harmful bacteria to grow. Apples are naturally acidic, but the acidity can vary depending on the apple variety.
It is essential to ensure your apple butter has a pH of 4.6 or lower to prevent the growth of Clostridium botulinum. Adding lemon juice or apple cider vinegar helps achieve this acidity level consistently. Always follow tested recipes to guarantee a safe final product.

Step-by-Step Guide to Canning Apple Butter
Now that you have your equipment and ingredients, let’s delve into the step-by-step process of canning apple butter safely.
Preparing the Apples
- Wash and Peel: Thoroughly wash the apples and peel them. You can leave the peels on if you prefer a slightly more rustic texture, but this may affect the smoothness of the final product.
- Core and Chop: Core the apples and chop them into small, even pieces. This will help them cook down more quickly and evenly.
Cooking the Apple Butter
- Combine Ingredients: In a large pot or Dutch oven, combine the chopped apples, sugar, spices, and water or apple cider.
- Simmer and Stir: Bring the mixture to a simmer over medium heat. Once simmering, reduce the heat to low and cook, stirring frequently, until the apples are very soft and easily mashed. This may take several hours.
- Puree the Mixture: Once the apples are cooked through, use an immersion blender or transfer the mixture to a regular blender to puree it until smooth. Be careful when blending hot liquids.
- Cook Down to Desired Consistency: Return the pureed apple mixture to the pot. Continue to cook over low heat, stirring frequently, until the apple butter reaches your desired consistency. This process can take several hours, as the water evaporates and the sugars caramelize. The apple butter is ready when a spoonful placed on a cold plate doesn’t run.
- Add Acid: Stir in the lemon juice or apple cider vinegar. This is a crucial step for ensuring the acidity is high enough for safe canning.
- Keep Warm: Keep the apple butter warm while you prepare the jars.
Preparing the Jars and Lids
- Sterilize Jars: Wash jars in hot, soapy water. Rinse well. Sterilize them by boiling them in the water bath canner for 10 minutes. Keep jars hot until ready to fill.
- Prepare Lids: Heat the lids in hot (not boiling) water. This softens the sealing compound. Do not boil the lids, as this can damage the sealing compound.
Filling the Jars
- Fill Jars: Using a wide-mouth funnel, fill the hot jars with hot apple butter, leaving 1/4-inch headspace.
- Remove Air Bubbles: Use a bubble remover or a clean utensil to gently release any trapped air bubbles.
- Wipe Jar Rims: Wipe the rims of the jars with a clean, damp cloth to remove any spills or residue.
- Place Lids and Rings: Place a lid on each jar, and then screw on a ring fingertip tight. Do not overtighten.
Processing in a Boiling Water Bath Canner

- Process for the Correct Time: Bring the water to a rolling boil. Process the jars for the recommended time, adjusting for altitude.
- Pints: 10 minutes (0-1,000 feet), 15 minutes (1,001-6,000 feet), 20 minutes (above 6,000 feet)
- Half-Pints: 10 minutes (0-1,000 feet), 15 minutes (1,001-6,000 feet), 20 minutes (above 6,000 feet)
- Turn Off Heat and Wait: After processing, turn off the heat and let the jars sit in the canner for 5 minutes before removing them.
- Remove Jars and Cool: Carefully remove the jars from the canner using a jar lifter and place them on a towel-lined surface to cool. Leave at least 1 inch of space between jars.
Checking for Seals and Storing Apple Butter
- Check for Seals: As the jars cool, you should hear a popping sound, indicating that a vacuum seal is forming. After 12-24 hours, check the seals by pressing down on the center of the lid. If the lid doesn’t flex, it’s sealed. If the lid flexes, the jar is not properly sealed and needs to be reprocessed with a new lid or refrigerated.
- Remove Rings: Once the jars are completely cool and sealed, remove the rings. This prevents moisture from accumulating and causing rust.
- Label and Store: Label the jars with the date and contents, and store them in a cool, dark, and dry place. Properly canned apple butter can be stored for up to 18 months.
Troubleshooting Common Canning Issues
Even with careful preparation, canning can sometimes present challenges. Here are a few common issues and how to address them.
- Jars Not Sealing: This can be caused by a number of factors, including nicks or cracks in the jar rim, insufficient headspace, or improper processing. Reprocess with a new lid within 24 hours or refrigerate.
- Siphoning: This occurs when liquid escapes from the jars during processing. Ensure jars are not overfilled, and avoid drastic temperature changes during processing.
- Mold Growth: Mold growth indicates spoilage and is a sign that the jars were not properly sealed or processed. Discard the contents without tasting.
- Discoloration: Some discoloration of apple butter is normal, especially over time. However, if the apple butter has an unusual color or odor, discard it.

Varieties like Golden Delicious, Jonathan, McIntosh, Rome, and Fuji are popular choices and can be used alone or in combination. Using a mix of apples contributes to a more complex and delicious flavor profile in the finished apple butter.
Ultimately, the best apples are the ones you enjoy the most, but consider those that break down easily during cooking. Avoid using overly ripe or bruised apples, as these can affect the quality and texture of the apple butter. The goal is to create a smooth, flavorful spread, so choosing apples that cook down well is paramount.
How long should I process apple butter in a water bath canner?
Processing time for apple butter in a water bath canner depends on your altitude and the size of your jars. For pints (16 oz) or smaller, process for 10 minutes at altitudes of 0-1,000 feet above sea level. Increase the processing time by 5 minutes for every 1,000 feet of altitude above that base.
For quarts (32 oz) jars, the processing time is longer. Process for 15 minutes at altitudes of 0-1,000 feet, increasing by 5 minutes for each additional 1,000 feet in altitude. Be sure the water covers the jars by at least 1-2 inches throughout the entire processing time, and start timing only when the water returns to a full rolling boil.
How do I know if my apple butter jars have sealed correctly after processing?
After processing, allow the jars to cool undisturbed for 12-24 hours. As the jars cool, the lids should begin to seal and you will likely hear a popping sound. This is a good indication that the lid has sealed.
To test for a proper seal, press down on the center of the lid. If the lid doesn’t flex up and down, and feels firm, it’s sealed correctly. If the lid flexes or pops, the jar hasn’t sealed properly and should be refrigerated immediately and consumed within a few days or reprocessed with a new lid following the same canning procedure.
What are the common mistakes to avoid when canning apple butter?
One common mistake is using too much sugar in the apple butter. Excessive sugar can interfere with heat penetration and potentially affect the safety and texture of the final product. Stick closely to a tested recipe to ensure the proper ratio of ingredients and avoid the risk of spoilage.
Another frequent error is not processing the apple butter for the correct amount of time, particularly when adjusting for altitude. Insufficient processing can lead to inadequate heat penetration and the survival of harmful bacteria.
