Are you a seafood enthusiast looking to elevate your culinary skills? Have you ever considered the satisfaction of canning your own tuna? Well, look no further! At Gio's Fish Market, your go-to online seafood supplier at, we're excited to present you with a comprehensive step-by-step guide on how to can tuna right in the comfort of your kitchen. With this easy-to-follow process, you'll have delicious, homemade canned tuna that's far superior to anything you'll find on a grocery store shelf.

Step 1: Acquire the Finest Catch

Begin your culinary journey by selecting the star of the show – fresh Albacore Loins. At Gio's Fish Market, we pride ourselves on offering top-notch boneless, skinless tuna fillets and Whole Albacore that are ideal for canning. But don't limit yourself – you can also experiment with other varieties like Salmon. Quality is paramount, so always choose seafood from reputable and health-approved facilities like ours.

Step 2: Gather the Tools

For this delightful endeavor, you'll need the appropriate equipment. You can find suitable jars, lids, and rings at hardware stores or online. Opt for ½ pint or pint jars, which make for perfect serving sizes. If you're new to canning, consider investing in a pressure cooker to expedite the process. Remember, a larger cooker lets you work with multiple jars simultaneously, streamlining the overall experience.

Step 3: Preparing the Fish and Jars

Now comes the exciting part – preparing the fish and jars for canning. Begin by cross-cutting the Albacore Loins into 4-5 inch "logs" that are as close to the diameter of the jar as possible, ensuring they fit snugly inside the jars, (the space for air inside the jar the better!). Start by adding a splash of olive oil at the bottom of each jar, followed by the fish pieces. Sprinkle a pinch of Kosher salt over the fish and add a couple of ounces of olive oil (or water) to fill any remaining air gaps. Be sure you leave about 3/4 inch of space at the top of each jar – this "Headspace" is crucial to prevent overflow and ensure a secure seal.

Step 4: Ensure a Clean Seal

Sanitation is key to successful canning. Make sure to thoroughly sanitize the jars, lids, and rings. You can achieve this by running them through a hot dishwasher cycle or by hand-washing in hot, soapy water. Heat the jars in the oven at 325°F for about 20 minutes, and simmer the lids and rings in a pot of hot (not boiling) water for the same duration. Cleanliness ensures a proper seal and extends the shelf life of your canned tuna.

Step 5: Seal the Deal

Assemble the jars with care. Place a clean lid on each jar and secure it with a ring, leaving it slightly snug – don't overtighten.

Step 6: Cook to Perfection

Set up your pressure cooker by adding around 2 inches of water to the bottom. Arrange the jars in a circular pattern the cooker, ensuring they're not touching. If your cooker is large enough you can use a spacer and stack 2 rows inside, greatly cutting down your total production time by cooking twice as much per batch. Follow your pressure cooker's instructions to seal it properly and achieve the desired pressure, usually between 10 to 15 pounds of pressure. Detailed instructions can be found HERE Let the cooker run for about 90 minutes, adjusting the heat as needed to maintain a steady, controlled rocking motion on the pressure weight on top of the cooker.

Step 7: Patience is a Virtue

After cooking, turn off the heat and let the cooker cool down naturally. This process might take an hour or more, but it's vital for safety. (Do not attempt to cooler your cooker with cold water!) Once the pressure is fully released, carefully remove the jars one by one and place them on a towel-covered surface. Over the next few hours, listen for the satisfying "snap" or "ping" that signals a successful seal.

Step 8: Enjoy Your Delicious Creations

Congratulations, you've done it! Once the jars have cooled, clean them off, remove any residue, label as desired, and proudly store them in your cupboard. Your homemade canned tuna can stay deliciously preserved for up to a few years. Feel free to experiment with different herbs and spices for unique flavor profiles. At Gio's Fish Market, we encourage creativity – from garlic cloves and fresh Rosemary to a touch of jalapeno for heat, the possibilities are endless.
