The method is basic. Infuse some garlic and herbs in a nice olive oil, and then gently poach the spice-rubbed tuna in this delicious bath. I cooked mine sort of medium-rare-medium, so there was a bit of pink inside. But, if you like you tuna cooked all the way through, that’s OK, you’re not a bad person. As you watch this recipe don’t worry about all that oil, since it’s just used to cook the fish in, and very little actually makes it onto the plate.  Another trick with this method is to add the tuna to the hot oil, and then just turn it off and let it cool in the infused olive oil. You can then store the tuna and oil in the fridge and use it to crumble over a salad. You may never use canned tuna again! This is referred to as “tuna confit” by some. By the way, Tombo tuna is also known as Albacore, which is the type of tuna most commonly canned. It’s also easier to find, and cheaper, than Ahi, which is that dark red fleshed tuna you’ve seen me use before.
