For 10 years the horseradish crusted ahi tuna with miso aioli has been the most popular dish at Terrapin Restaurant. I use sushi grade #1 tuna for this dish and sear it briefly on both sides in a non-stick pan, leaving the center raw. Really, the key to this dish is the freshness of the tuna. At Terrapin, we get fish deliveries from a sushi supplier almost every day. The best way for you to get sushi grade tuna, at its freshest, is to ask your local fish store which days of the week their #1 tuna is delivered and make this dish on one of those days.
