In recent decades, Hawaiian chefs have created a sumptuous new regional cuisine, often featuring the local tuna. Here’s a smoked version of a Big Island favorite.
Prepare the smoker for barbecuing, bringing the temperature to 180°F to 200°F.
Mix the marinade ingredients in a large glass measuring cup. Place the tuna steaks in a shallow, nonreactive dish or a plastic bag and pour the marinade over the tuna. Allow the steaks to sit at room temperature for 20 to 30 minutes.
