Understanding the Mirro Pressure Canner
The Mirro pressure canner is designed to create a sealed environment that allows for high-temperature cooking, which is necessary for safely preserving low-acid foods like vegetables, meats, and poultry. Unlike water bath canning, which is suitable for high-acid foods such as fruits and jams, pressure canning ensures that harmful bacteria are destroyed, making your canned goods safe for consumption.
Getting Started with Your Mirro Pressure Canner
Before you start canning, it's essential to familiarize yourself with your Mirro pressure canner. Here’s what you need to know:
Components of the Mirro Pressure Canner
Understanding the various parts of your canner will help you use it effectively. The primary components include:
- Base: The main body where you place your jars and water.
- Lid: A heavy, locked lid that creates a seal during the canning process.
- Weight or Pressure Regulator: This maintains the pressure inside the canner.
- Safety Valve: A safety feature that releases excess pressure.
- Jars and Lifter: Necessary for placing jars inside and removing them safely.
Preparing for Canning
Before using your Mirro pressure canner, follow these steps for preparation:
1. Read the Manual: Always start by reading the Mirro pressure canner manual thoroughly. Familiarize yourself with the specific instructions related to your model.
2. Gather Your Supplies: Ensure you have all necessary materials, including jars, lids, and the food you plan to can.
3. Sanitize Jars: Clean jars and lids in hot, soapy water or run them through a dishwasher cycle.
4. Prepare Food: Wash, peel, and chop the food you intend to can according to the recipe you are following.
Using the Mirro Pressure Canner
Now that you are prepared, it’s time to use your Mirro pressure canner.
Step-by-Step Instructions
Follow these steps for effective pressure canning:
1. Add Water: Pour the recommended amount of water into the canner (usually 2-3 inches, depending on the recipe).
2. Load the Jars: Place filled jars into the canner using a jar lifter, ensuring they do not touch each other.
3. Seal the Lid: Secure the lid on the canner, ensuring the rubber gasket is properly positioned for a tight seal.
4. Heat the Canner: Turn on the burner to high heat. Allow steam to escape from the vent for about 10 minutes to ensure the canner is vented.
5. Stabilize Pressure: Place the weight or pressure regulator on the vent. Monitor the pressure gauge until it reaches the desired pressure (usually 10-15 psi depending on the recipe).
6. Start Timing: Once the correct pressure is reached, start your timer according to the recipe.
7. Cool Down: After the time is up, turn off the heat and allow the canner to cool down naturally. Once the pressure gauge reads zero, carefully remove the weight and open the lid.
Post-Canning Care
After canning, it’s essential to check your jars:
- Inspect Seals: Ensure that all jar lids are sealed properly. The center of the lid should be indented.
- Label and Store: Label jars with the contents and date. Store in a cool, dark place.
- Clean the Canner: Clean the inside of the pressure canner with warm, soapy water after each use.

Proper maintenance of your Mirro pressure canner extends its lifespan and ensures safe canning.
Regular Checks and Cleaning
- Gasket Inspection: Regularly check the rubber gasket for cracks or wear. Replace if necessary.
- Vent Pipe Cleaning: Ensure the vent pipe is clear of obstructions to allow steam to escape properly.
- Pressure Gauge Testing: Have your pressure gauge tested annually to ensure it is functioning accurately.
Safety Precautions
Canning can be a safe and rewarding process if done correctly. Here are some safety tips to keep in mind:
- Follow Recipes: Always use tested recipes for canning to ensure safety.
- Don’t Overfill: Ensure jars are filled to the appropriate headspace to allow for expansion.
- Supervise the Canner: Never leave a pressure canner unattended while in use.
- Release Pressure Safely: Always allow the canner to cool down naturally before attempting to open it.
