Ex-pat Ahi Poke
This poke is so that all Hawaii people not living in Hawaii (ex-pat Hawaii folks) can get their fix. It doesn't use the traditional limu/ogo (seaweed) or inamona (smashed kukui nuts). Inamona has traditional Hawaiian medicinal use as a laxative, so not everone tolerates it well. Moreover, if you do not live in Hawaii, these things are very hard to get. Believe me, I've tried.
This recipe is mostly from my dad, but I also checked online and my trusty Sam Choy cookbook. When I was trolling the online poke recipes, substituting macadamia nuts for inamona came up a few times, but I don't recommend this.
The most important thing is to get the "freshest-fresh ahi". Fresh fish, weirdly enough, will not smell 'fishy'. It's best buy a chunk rather than pre-sliced. Air degrades fish pretty quickly into a mushy mess.
