It was labeled as red snapper and priced relatively low. Most of what is sold as red snapper is not actually red snapper but some crappier cheaper snapper which store owners use to rip you the fuck off. I know you are a sucker mark so I figured I would explain that to you. This is one of the many reasons I prefer to purchase my fish whole. I immediately recognized that this fish is not a red snapper, obviously, but rather it is a yellowtail snapper which is far superior. Score.
I cooked this guy whole but my pictures turned out like shit, which is surprising because I'm basically the best food photographer in the history of the known universe. I decided to pass on the mango salsas and elaborate stuffings for something simpler so I could experience the true flavor of my prized catch.
Cilantro, for garnish
Mix everything but the cilantro in a small bowl. Shove it inside your fish. Place a large piece of aluminum foil on a baking sheet, brush the whole thing with more oil, and sprinkle more sea salt all over. Place your fish down, wrap it up, and toss it in a 350 degree oven for 40 minutes. Let it sit in the foil for another 7 minutes after you pull it from the oven. Garnish with cilantro. Eat it.
