Hi,
Other than fluke, bluefish is my favorite when prepared as follows:
filet fish and remove skin.
marinade filets for at least a few hours, but sometimes
we do it
for a few days, in a ziplock bag or container with the following:
1 cup of good olive oil
2 tblsps of soy sauce.
a touch of lime juice. (sometimes we skip this if we don't have any.)
Grill on a very hot grill. Usually 4-5 min on each side.
happy eating,
john
