About swordfish:

Many varieties of fish have a flaky texture, but swordfish has more of a meaty texture. It is sold in steaks. Swordfish is a mild-tasting, white fish.  Reddish areas have a stronger flavor and can be cut off and discarded. Trim off the tough and inedible skin before or after cooking.

Swordfish is often sold frozen and the quality of frozen is usually pretty good, but make sure that the reddish areas are red, not brown.

Can I substitute another kind of fish for the swordfish in this recipe?

Yes!  Substitute other meaty fish such as tuna, halibut, mahi-mahi or salmon in place of the swordfish.  You can use the same marinade and top with the avocado mayonnaise.

Ingredients

AVOCADO MAYONNAISE:

  • large Hass avocados
  • 1/3 cup mayonnaise
  • 1 tablespoon freshly squeezed lime juice
  • 3/4 teaspoon Tabasco sauce
  • 1/4 teaspoon salt

MARINADE:

  • 1 cup sliced green onions
  • 3/4 cup packed cilantro leaves
  • 3 tablespoons extra virgin olive oil
  • 3 tablespoons freshly squeezed lime juice
  • tablespoons grated lime zest
  • tablespoons packed light brown sugar
  • 1 tablespoon minced jalapeno (seeds removed)
  • 1/2 teaspoon salt
  • 1/2 teaspoon freshly ground black pepper

SWORDFISH:

  • Four 8-ounce 1-inch thick swordfish steaks

Instructions

PREPARE THE AVOCADO MAYONNAISE:

  • Combine all ingredients in a food processor. Process; scraping down sides to work in ingredients until all is smooth. Cover and refrigerate until ready to use. Clean out processor bowl.

PREPARE MARINADE:

  • In the food processor bowl, combine the onions, cilantro, oil, juice, zest, sugar, jalapeño, salt and pepper. Process, then transfer to a pyrex dish. Add the swordfish, cover, and marinate in the refrigerator, turning once or twice, for 1 hour.

GRILL:

  • Meanwhile, preheat the grill to medium-high. When the grill is ready, remove the fish pieces from the marinade (reserve the marinade), and lay them on the rack. Cover and grill, basting with the marinade and turning once, until the fish is done to your liking, about 8 minutes total for fish slightly undercooked at the center.
  • Transfer the fish to plates, top with a dollop of the mayonnaise, and serve immediately.
