Frequently Asked Questions (FAQs)

What is blackened swordfish?

Blackened swordfish is fish that is seasoned, and then seared at high heat until the surface starts to blacken without burning. This method of cooking makes the swordfish juicy and fragrant.

Is swordfish good meat?

Its mild taste makes it a particularly good choice for those who are unsure if they like fish. Reddish areas have a stronger flavor and can be cut off. Swordfish is particularly good grilled, either as a steak or kebabs, and it’s also delicious broiled and sautéed.

Can you eat the dark part of swordfish?

That dark, nearly black area in the middle of your tuna or swordfish steak is nothing bad or unhealthy, although you may not like its strong flavor. It is a muscle that is rich in myoglobin, a blood pigment.

What to serve with blackened swordfish?

A simple squeeze of lemon is always a perfect addition. But there are so many other flavors that go really well with seafood. We love eating it with some wasabi mayonnaise or Jalepeno Orange Relish. You could try a mango salsa or even a Spicy Tartar sauce.
