Seared King Fish and Mustard Cream and Caper Sauce

READY IN: 20mins
Recipe by Fleur Winger

King Fish is a popular NZ game fish. Mostly cooked as steaks. I made this sauce up, as sometimes King Fish can be dry if not fresh enough. The sauce is also great with Tuna or Steak.

Excellent recipe for the fish & the sauce was also awesome. While in Florida, we were told by several people that the kingfish we caught would be extremely strong tasting & would need to be marinated... It was awesome without any marinating.... Sauce was great on several grilled types of fish!
