Planked Whitefish With Cilantro-Lime Butter Recipe


I'm making strides at becoming a seafood eater. If it's fried, I'll most likely at least try it, but I want to step it up and eat fish not just because it has a golden crunchy crust, but because it's fish.

The next step to achieving this was making a mild flavored fish, planked, and mixed with other flavors that I knew I already liked—that's where this recipe for a cedar planked whitefish with cilantro-lime butter came in. Any mild, flaky whitefish will do; my fishmonger had fresh flounder. Coming from a grilling mindset, I thought about rubs, and what would match well with wood flavor from planking—I opted for a cedar plank.

Once the fish was opaque and started to flake, after about 20 minutes over an indirect, medium heat, I slathered on a tasty compound butter of cilantro, serrano chile, and lime.

All of my inclinations here were right on. While both the woody flavor of the plank and butter were excellent additions, they only complemented and didn't mask the fish. It's a great way to enjoy fish, particularly for seafood eaters in training.
