Kampachi with Ali’i Mushrooms

On the Big Island, CanoeHouse is about as iconic as you can get. One of the star attractions of the Mauna Lani, Auberge Resorts Collection, it was originally helmed by the legendary Alan Wong. Now it’s run by Chef Matt Raso and his lovely wife, Yuka, who met working at one of Nobu's first restaurant kitchens. The food at CanoeHouse is a heady fusion of Japanese and Hawaiian, using ingredients sourced from the volcanic soils and clear warm seas close to home. On a recent trip, we were wowed by chef Matt's kampachi fish, subtle and tender inside, with a salty-dashi-crispy skin. Don't be put off by the Japanese ingredients, easily procured online, on Sawtelle, or in many of our more upscale markets. Kampachi is Hawaiian yellowtail, farmed off the Kohala Coast in innovative and sustainable practice, but yellowtail will do just as well.
