Safe Methods for Canning Zucchini Apple Pie Filling

Canning zucchini apple pie filling is a great way to preserve the flavors of summer and fall for use throughout the year. However, because zucchini is a low-acid vegetable, it requires careful handling to ensure safety and prevent spoilage. This post explains how to can zucchini apple pie filling safely, with clear steps and tips to help you enjoy your homemade filling without worry.

Understanding the Importance of Safety in Canning

When canning any low-acid food like zucchini, safety is the top priority. Low-acid foods can harbor bacteria such as Clostridium botulinum, which causes botulism, a serious foodborne illness. Unlike high-acid foods (like fruits), low-acid foods need to be processed using a pressure canner or have acids like vinegar (think pickles) or lemon juice added to them to make them safe to water bath.

With the addition of the lemon juice the pH of this recipe is below 4.6, making it appropriate to water bath can. If you are concerned, you can always add even more lemon juice or pressure can it. (Pressure canning will result in very soft chunks though.)

Preparing Zucchini Apple Pie Filling for Canning

Ingredients and Equipment

• 12 cups zucchini, peeled and chopped

• 4 cups apple juice

• 2 cups sugar

• 1 cup brown sugar

• 1/2 cup ClearJel (modified cornstarch)

• 1 teaspoon cinnamon

• 1/4 teaspoon nutmeg

• 1/8 teaspoon ground cloves

• 1/3 cup lemon juice (to increase acidity)

• Water bath canner

• Canning jars with lids and bands

• Large pot for cooking filling

• Ladle and funnel for filling jars

  
  

Step-by-Step Preparation

1. Select Fresh Produce

   Choose firm, large zucchini. Wash thoroughly. Peel and dice.

   

2. Prepare the Filling

   

   Cook the zucchini with half of the apple juice for 10 minutes. This infuses the apple taste into the zucchini.

   

   Strain out the zucchini.

   

   Mix the dry ingredients together.

   Add all ingredients except zucchini to pot with remaining apple juice. Boil for 1 minute.

   Remove from the heat and gently fold in the cooked zucchini.

   
   

3. Hot Pack Method

   

   Pack it hot into clean, hot jars. Use a wooden chopstick to remove any trapped air bubbles.

   
   

4. Leave Proper Headspace

   Leave about 1 inch of space between the filling and the jar rim to allow for expansion during processing.

   
   

5. Wipe the rims of the jars with a clean cloth to ensure a good seal, then place the lids on top and secure the rings until they are fingertip tight. (For quality, American made Superb canning lids and jars follow this link and use the coupon code WP20 to get 20% off your purchase.) 

6. Process the jars in a boiling water bath (electric or regular) for 25 minutes if at sea level. (Remember to adjust the processing time for your elevation.)

   

   Don't start the timer until after the water has come to a rolling boil. After the processing time has elapsed, remove the lid, turn off the heat and allow the jars to cool for 5 minutes.

Storing and Using Your Canned Zucchini Apple Pie Filling

• Remove the jars from the water bath and let them cool on a heat resistant surface for 24 hours.

• Check seals by pressing the center of each lid. If it does not flex, the jar is sealed.

• Label jars with the date and contents.

• Store in a cool, dark place. Properly canned filling can last up to three years.

• Once opened, refrigerate and use within a week.

  

Common Mistakes to Avoid

• Increasing the amount of Zucchini.

• Skipping the addition of lemon juice.

• Not following tested recipes or processing times.

• Not increasing time for increased elevation.

• Overfilling jars or not leaving enough headspace.
