Pressure canning is a fantastic way to preserve food, extending its shelf life significantly and making it readily available for future meals. But when it comes to cooked chicken, the question of whether you can safely pressure can it often arises. The answer is a resounding yes, but understanding the nuances and following proper procedures is absolutely crucial. This comprehensive guide will walk you through everything you need to know about pressure canning cooked chicken, ensuring a safe and delicious outcome.
Why Pressure Can Cooked Chicken?
There are several compelling reasons to pressure can cooked chicken. First and foremost, it’s a great way to reduce food waste. If you’ve cooked too much chicken for a meal, or have leftovers from a roasted chicken, pressure canning allows you to preserve it instead of throwing it away. Secondly, it provides a convenient way to have ready-to-eat chicken on hand for quick meals like soups, salads, casseroles, and more. Lastly, pressure canning cooked chicken is an excellent option for emergency preparedness. Having jars of shelf-stable protein can be a lifesaver in unforeseen circumstances.
Benefits of Pressure Canning Cooked Chicken
Consider the sheer convenience of having cooked chicken readily available. Imagine a busy weeknight; instead of defrosting raw chicken and cooking it, you simply open a jar of pressure-canned chicken and add it to your favorite recipe. This saves time and effort, making meal preparation significantly easier. Furthermore, pressure canning is a cost-effective way to preserve food. Buying chicken in bulk and then pressure canning it can be more economical than buying pre-cooked chicken from the store.
Understanding the Science Behind Pressure Canning
Before diving into the specifics of pressure canning cooked chicken, it’s vital to understand the science behind the process. Pressure canning uses high heat and pressure to kill harmful bacteria, particularly Clostridium botulinum, which causes botulism. This bacteria thrives in low-acid environments and can produce a deadly toxin. Pressure canning achieves temperatures higher than boiling water (212°F or 100°C), which is necessary to eliminate these spores.
Why Pressure Canning is Essential for Low-Acid Foods
Foods are categorized as either high-acid or low-acid. High-acid foods like fruits and pickles can be safely processed in a boiling water bath canner. Low-acid foods, including meats, poultry, vegetables, and seafood, require a pressure canner because the higher temperatures are necessary to destroy Clostridium botulinum spores. Chicken, being a low-acid food, falls into this category. Therefore, pressure canning is the only safe method for preserving cooked chicken at home.
Essential Equipment for Pressure Canning Cooked Chicken
To safely pressure can cooked chicken, you’ll need specific equipment. A pressure canner is the most important piece. Make sure it’s in good working order and that the dial gauge (if applicable) is accurate. You’ll also need canning jars, lids, and bands. Jars should be specifically designed for canning, as they are made to withstand the high temperatures and pressures involved. Other essential tools include a jar lifter, a wide-mouth funnel, a lid wand (magnetic or non-magnetic), and a bubble remover (or a non-metallic spatula). A clean workspace is also important.
Choosing the Right Pressure Canner
There are two main types of pressure canners: dial gauge canners and weighted gauge canners. Dial gauge canners have a gauge that indicates the pressure inside the canner. These gauges need to be tested annually for accuracy. Weighted gauge canners use weights to regulate the pressure. They are generally considered more reliable and require less maintenance. The choice between the two depends on personal preference. Regardless of the type you choose, always follow the manufacturer’s instructions carefully.
Preparing Your Canning Jars and Lids
Proper preparation of your jars and lids is crucial for a successful canning process. Jars should be thoroughly washed in hot, soapy water and rinsed well. They should then be kept hot until they are filled. You can keep them hot by placing them in a simmering pot of water or by running them through a hot cycle in your dishwasher. Canning lids used to need simmering in hot water to soften the sealing compound, but most modern lids no longer require this step. Always refer to the manufacturer’s instructions on the lid packaging. New lids are essential for proper sealing.
Step-by-Step Guide to Pressure Canning Cooked Chicken
Now, let’s delve into the step-by-step process of pressure canning cooked chicken. This process requires precision and attention to detail to ensure safety.
Preparing the Chicken
The first step is to prepare the cooked chicken. You can use leftover roasted chicken, boiled chicken, or any other method of cooking. Remove the skin and bones, and cut the chicken into bite-sized pieces or cubes. It’s important to ensure that the chicken is cooked thoroughly before canning.
Packing the Jars
There are two methods for packing the jars: raw pack and hot pack. While you are canning cooked chicken, it is considered a hot pack. For the hot pack method, heat the cooked chicken pieces in broth or water before packing them into the jars. This helps to remove air from the jars and improve the vacuum seal. Pack the hot chicken pieces into the hot jars, leaving 1 1/4 inches of headspace at the top of the jar. Headspace is the space between the top of the food and the lid.
Adding Liquid and Removing Air Bubbles
After packing the chicken, add hot broth or water to the jars, maintaining the 1 1/4 inches of headspace. Use a bubble remover or a non-metallic spatula to release any trapped air bubbles by running it along the inside of the jar. This is important because trapped air can interfere with the sealing process.
Wiping the Jar Rims and Applying Lids and Bands
Wipe the jar rims with a clean, damp cloth to remove any food particles or residue. This ensures a proper seal. Place the lids on the jars and screw on the bands until they are fingertip tight. Do not overtighten the bands, as this can prevent the air from escaping during processing.
Processing in the Pressure Canner
Place the filled jars in the pressure canner, following the manufacturer’s instructions. Add the recommended amount of water to the canner. Lock the lid securely. Vent the canner by allowing steam to escape for 10 minutes before closing the vent or adding the weight. Once the canner reaches the correct pressure (10 PSI for dial gauge canners or 10 PSI with a weighted gauge canner at altitudes of 0-1000 feet; adjust for higher altitudes), begin timing the processing. Process pint jars for 75 minutes and quart jars for 90 minutes.
Cooling and Checking the Seals
After processing, turn off the heat and allow the canner to cool naturally until the pressure returns to zero. Do not force the cooling process by running cold water over the canner, as this can cause the jars to break. Once the pressure is at zero, carefully remove the lid and let the jars cool completely on a towel-lined surface for 12-24 hours. After cooling, check the seals by pressing down on the center of each lid. If the lid flexes or pops, it has not sealed properly and should be reprocessed with a new lid or refrigerated and used within a few days. If the lid is concave and does not flex, the jar is properly sealed.
Safety Precautions for Pressure Canning
Pressure canning involves high heat and pressure, so it’s essential to follow safety precautions to prevent accidents and ensure the food is safe to eat. Always follow the manufacturer’s instructions for your specific pressure canner. Never attempt to process low-acid foods in a boiling water bath canner. Ensure that your jars and lids are in good condition and that you are using new lids for each batch. Be careful when handling hot jars and steam. If you are unsure about any aspect of the canning process, consult a reliable source, such as your local extension office.
Altitude Adjustments
Altitude plays a significant role in pressure canning. At higher altitudes, water boils at a lower temperature, so you need to increase the processing pressure to achieve the necessary temperature to kill bacteria. Refer to a canning guide or your pressure canner’s instructions for the appropriate pressure adjustments based on your altitude. Typically, pressure needs to be increased by 1 PSI for every 1,000 feet above sea level for dial gauge canners. Weighted gauge canners usually have different weight settings for different altitudes.
Dealing with Unsealed Jars
If a jar does not seal properly after processing, there are two options: reprocess it immediately or refrigerate it and use the contents within a few days. To reprocess, use a new lid and process for the full recommended time. Inspect the jar rim for any nicks or cracks that may have prevented the seal. Reprocessing is not always recommended, so it’s best to use the unsealed jar promptly. Discard the contents of any jar that shows signs of spoilage, such as a bulging lid, a foul odor, or mold.
Troubleshooting Common Pressure Canning Problems
Even with careful attention to detail, problems can sometimes arise during pressure canning. Understanding how to troubleshoot these issues can save you time and frustration.
Siphoning
Siphoning refers to the loss of liquid from the jars during processing. This can be caused by overfilling the jars, inadequate venting of the canner, or sudden pressure fluctuations. To minimize siphoning, ensure that you are leaving the correct headspace, venting the canner properly, and allowing the pressure to drop naturally after processing.
Jar Breakage
Jar breakage can occur due to sudden temperature changes, using damaged jars, or packing the jars too tightly in the canner. To prevent jar breakage, avoid drastic temperature changes, inspect your jars for cracks or chips before using them, and ensure that the jars are not touching each other inside the canner.
Food Spoilage
Food spoilage is the most serious problem that can occur during canning. It is usually caused by inadequate processing, improper sealing, or using contaminated ingredients. To prevent food spoilage, follow the recommended processing times and pressures, ensure that your jars are properly sealed, and use fresh, high-quality ingredients. Always inspect the contents of the jars before consuming them.
