The Canning Process: Step-by-Step Guide
Now that you have all the equipment ready, let’s delve into the canning process itself. Follow these steps closely to ensure the best results.
Step 1: Preparing the Fish
Begin by cleaning and preparing the fish.
- Scale and gut the fish if not already done by the fish seller.
- Rinse the fish thoroughly under cold water to remove any remaining scales or debris.
- Cut the fish into appropriate sizes for your jars. Depending on your preference, you can leave the fish whole or cut it into pieces.
Step 2: Sterilizing Jars
Before filling jars, it is crucial to ensure they are sanitized.
- Wash jars and lids in hot soapy water, or run them through a dishwasher.
- Place them in a preheated oven at 200°F (93°C) for about 10 minutes.
- Alternatively, immerse them in boiling water for a few minutes.
Step 3: Packing the Fish into Jars
Once the jars are sterilized, proceed to pack the fish.
- Layer the fish into each jar. You can sprinkle salt, pepper, or any seasonings between layers if desired.
- If adding vegetables, you can place them in the jar with the fish for added flavor.
Make sure to leave a headspace of at least 1 inch (2.54 cm) from the top.
Step 4: Sealing the Jars
- Wipe the rims of the jars with a clean, damp cloth to ensure a good seal.
- Place the lids on the jars and screw on the metal bands until they are fingertip-tight. Avoid over-tightening as it may impede sealing.
Step 5: Preparing the Pressure Cooker
Fill your pressure cooker with water as per the manufacturer’s instructions. Typically, you will need about 2-3 inches (5-7.5 cm) of water at the bottom.
Step 6: Canning the Fish
- Place the filled jars inside the pressure cooker, ensuring they are upright and not touching one another.
- Lock the lid into place and heat it until steam begins to escape.
- Once steam is visibly escaping, allow it to vent for 10 minutes before sealing it completely.
Step 7: Processing Time
The processing time for fish jars depends on the type of fish and jar size. Here are some general recommendations:
| Type of Fish | Pint Jars | Quart Jars |
|---|---|---|
| Tuna | 1 hour 30 minutes | 2 hours |
| Salmon | 1 hour 15 minutes | 1 hour 45 minutes |
Make sure to adjust processing times according to your altitude. Use a reliable canning guide to find the correct processing times for your specific conditions.
Step 8: Cooling and Storing the Jars
After the processing time is complete, turn off the heat and allow the pressure cooker to cool down naturally. Once the pressure has returned to normal, carefully open the lid and use a jar lifter to remove the jars from the cooker.
- Allow the jars to sit undisturbed on a clean towel or cooling rack for 12-24 hours.
- Once cooled, check that the lids have sealed properly. Press the center of each lid; if it pops back, the jar hasn’t sealed and should be refrigerated and consumed within a few days.
Store your sealed jars in a cool, dark location, and enjoy them within a year for the best quality.
