Preserving potatoes through pressure canning is a fantastic way to ensure a steady supply of this versatile vegetable for your culinary adventures. Whether you crave creamy mashed potatoes, crispy fried slices, or hearty additions to soups and stews, having jars of home-canned potatoes on hand can elevate your meals and streamline your cooking process. In this guide, we’ll walk you through the simple steps of pressure canning potatoes to perfection.
Why Pressure Canning?
Pressure canning is essential for preserving low-acid foods like potatoes safely. Unlike high-acid foods that can be preserved through water bath canning, low-acid foods require the higher temperatures achieved through pressure canning to eliminate the risk of harmful bacteria such as Clostridium botulinum. By following proper procedures, you can ensure the long-term shelf stability and safety of your canned potatoes.
Ingredients and Equipment:
Before diving into the canning process, gather your ingredients and ensure you have the necessary equipment on hand:
Ingredients:
– Potatoes (choose fresh, firm potatoes, preferably of uniform size)
– Salt (1/8th teaspoon per quart jar)
Equipment:
– Pressure canner
– Quart-sized canning jars with lids and bands
– Jar lifter
– Canning funnel
– Potato peeler
– Knife
– Cutting board
– Large pot for blanching
– Clean kitchen towels
– Timer
Step-by-Step Guide to Pressure Canning Potatoes:
Follow these simple steps to ensure successful pressure canning of your potatoes:
1. Preparation:
– Wash the potatoes thoroughly under running water to remove any dirt or debris.
– Peel the potatoes and cut them into uniform pieces. You can choose to leave them whole or cut them into chunks or slices, depending on your preference.
– Prepare your pressure canner according to the manufacturer’s instructions. Ensure the seals are intact and the vents are clear.
2. Blanching:
– Fill a large pot with water and bring it to a boil.
– Carefully add the potato pieces to the boiling water and blanch them for 2-3 minutes. Blanching helps preserve the quality of the potatoes during the canning process by stopping enzyme activity.
3. Packing the Jars:
– Using a clean canning funnel, pack the blanched potato pieces into the quart-sized canning jars, leaving about an inch of headspace at the top of each jar.
– Add 1/8th teaspoon of salt to each jar to enhance the flavor of the potatoes.
4. Filling with Water:
– Pour hot water over the potatoes in each jar, maintaining the 1-inch headspace. Ensure all the potatoes are covered with water to prevent discoloration and ensure even cooking during processing.
5. Removing Air Bubbles and Sealing:
– Run a clean knife or spatula along the inside edge of each jar to release any trapped air bubbles.
– Wipe the rims of the jars with a clean, damp towel to ensure a proper seal.
– Place the lids on the jars and secure them with the bands, tightening just until finger tight.
6. Canning Process:
– Place the filled jars in the prepared pressure canner, ensuring they are not touching each other or the sides of the canner.
– Secure the lid of the pressure canner according to the manufacturer’s instructions, ensuring the vents are open.
– Bring the pressure canner to the appropriate pressure for your altitude (typically 10-11 psi for most locations).
– Process the jars at the required pressure for 90 minutes, adjusting the heat as needed to maintain a steady pressure.
7. Cooling and Storage:
– Once the processing time is complete, turn off the heat and allow the pressure canner to cool naturally. Do not attempt to force-cool the canner.
– Once the pressure has fully released and the canner is cool enough to handle, carefully remove the jars using a jar lifter and place them on a clean kitchen towel.
– Allow the jars to cool completely at room temperature. You may hear the satisfying “pop” of the lids sealing as they cool.
– Once cooled, check the seals of the jars by pressing down on the center of each lid. If the lid is firm and does not flex, the jar is properly sealed. Any unsealed jars should be refrigerated and used promptly. Remove the jar bands, this prevents any unsealed jars from going unseen.
– Label the sealed jars with the date of canning and store them in a cool, dark place. Properly canned potatoes can last up to 1 year or more in storage.
