For many people, cooking seafood sounds scary. I'm here to tell you, it is not! The most important part is the quality of the product itself. For this or any other recipe, make sure you are purchasing grade-A number 1 ahi tuna, fresh from a seafood market or a local fisherman you trust. If you can get a hold of some bluefin, do it! You will not be disappointed. This recipe also works well with albacore, but is a bit more delicate when slicing the finished product.
