Step-by-Step Guide to Canning Fish in a Pressure Cooker
Now that you have all the necessary supplies and ingredients, follow this step-by-step guide to successfully can fish in a pressure cooker.
Preparation
Clean and Cut the Fish:
Start by cleaning your fish properly. Remove scales, guts, and any other unwanted parts. Cut the fish into pieces suitable for your jars.Prepare Your Canning Jars:
Make sure to sterilize your jars in boiling water for about 10 minutes before you start packing them with fish. Keep the jars hot until you’re ready to fill them.
Packing the Fish
To pack the fish into the jars:
- Fill the sterilized jars with the fish pieces, leaving about 1-inch headspace at the top.
- Sprinkle salt (about 1 teaspoon per pint/jar) over the fish. This step is optional but enhances the flavor significantly.
- Pour boiling water or broth over the fish, maintaining the 1-inch headspace.
Removing Air Bubbles
After filling your jars, it’s essential to eliminate any trapped air bubbles. Insert a non-metallic spatula or bubble remover into the jar, gently moving it around to release any air.
Sealing Your Jars
Once your jars are packed and air bubbles are removed:
- Wipe the rims with a clean cloth or paper towel to remove any residue.
- Place the sterilized lids on top, ensuring they’re centered over the jar.
- Screw on the metal bands until they are fingertip-tight—don’t overtighten as it may prevent steam from escaping during processing.
Processing in the Pressure Cooker
The next step is to process your jars in the pressure cooker, which is crucial for safe preservation.
Loading the Pressure Canner
- Before loading your jars, add about 2 or 3 inches of water to the bottom of your pressure canner.
- Place the canner rack into the bottom to lift the jars above the water level.
Processing Times and Pressures
Here is a general guideline for processing times and pressures based on jar size:
| Type of Fish | Jars Size | Processing Time | Pressure (pounds) |
|---|---|---|---|
| Salmon | Pint | 75 minutes | 10-15 |
| Tuna | Pint | 100 minutes | 10-15 |
Remember, pressure and processing times can vary depending on your altitude, so check guidelines specific to your location.
Bringing the Pressure Canner to Temperature
- Secure the lid on the canner according to the manufacturer’s instructions.
- Heat on high until steam begins to escape from the vent pipe.
- Allow the steam to escape for about 10 minutes. This step is critical to ensuring that all air is expelled before sealing the canner.
- Close the vent and allow the pressure to build to the desired level indicated in your processing chart.
Finishing the Canning Process
Once your processing time is complete, turn off the heat and allow the pressure canner to cool down naturally.
Removing the Jars
- Carefully remove the lid and set it aside, allowing steam to escape.
- Use your jar lifter to remove the jars, placing them on a clean, dry towel or cooling rack.
Cooling and Sealing
Leave the jars to cool for 12 to 24 hours. As they cool, you should hear the satisfying “ping” sound, which indicates the seals are forming correctly. After the cooling period, check the seals by pressing the center of each lid; it should not flex up or down.
Storing Your Canned Fish
Proper storage is vital to ensure the longevity of your canned fish.
Best Practices for Storage
- Store the jars in a cool, dark place, such as a pantry or cellar.
- Avoid exposing jars to direct sunlight or heat sources.
- Label jars with the date of canning for reference.
