Fresh Yellowfin (ahi) tuna is best prepared simply. This Ahi Poke is about as simple as you can get, and yet the combination of the velvety tuna, sweet onions, nutty sesame oil and crunchy crystals of umami rich Alaea sea salt make this an addicting dish that will have you going back for seconds and thirds. While Poke is traditionally made with Kukui nuts in Hawaii, pine nuts have a similar texture and flavor and are much easier to find on the mainland.
