Hi Pat,
I rarely eat Mahi Mahi, mainly because it can sometimes be quite expensive, and also because like all ocean caught fish, it can contain significant amounts of Mercury, depending on where it is caught. However, I am quite fond of it's flavor, so I will have it a couple of times each year.
Mahi-Mahi is the Hawaiian name for dolphinfish. It has a sweet, mildly pronounced flavor, similar to swordfish. The lean meat is fairly firm in texture, though not steak-like, and it has large, moist flakes. It is also important not to confuse Mahi-Mahi with the mammalian dolphin, as it is not related in any way.
Any white, flaky Fish could be substituted in the recipe and it would taste very good I would imagine. I would think that you could substitute Tilapia if you prefer, since the texture of Tilapia is slightly firm and flaky and the flavor is mild and sweet. One of my personal favorites, and one which is also quite reasonably priced, is Cod. Cod has lean, moist meat with a mild, clean flavor and it’s large, tender flakes make it a lovely white fish to prepare.
As I've said, I do like Seafood, in any and all forms, and we are blessed here in Thomasville to have a local Fish Market where we can purchase Fresh Seafood daily, just like the Restaurants. Of course, I'm actually doubly blessed, since I attended school with two of the original Owner's children and every once in a while, I will get a "slight" break in the prices.
Have A Wonderful Weekend My Friend,
Phil
