How to choose the best Swordfish?
When you are buying Swordfish, look for fish that has firm flesh and is not slimy to the touch. It should have a "sea" or "salt water" smell, not overly fishy smelling. According to Seafood Source, the color will range between white, ivory to pink and orange, depending on what the swordfish are eating. When cooked, the Swordfish changes to a beige tone.
Prevention magazine states there is more of a risk of cross contamination if you rinse or wash your fish. It is not necessary and is more important that the fish is cooked to the proper temperature to kill any bacteria.
Also, make sure you wash your hands and any kitchen tools or cutting boards after handling raw fish.
According to the CDC, Swordfish should be cooked to 145°F or until the meat is opaque and flaky.
How to grill the Swordfish?
- Rub with olive oil and seasoning blend.
- Heat grill to medium high flame. Don't move the fish after it's on the grill. Let it cook, you will see the grill marks, cooking about 3 minutes. Flip the fish and cook the other side for another 3 minutes.
- Check the temperature with a meat thermometer. If it doesn't register 145°F, cook a few minutes longer.
