"When you think 'poached' you probably think 'salmon', but poaching is great for tuna, also. Done right (meaning very gently) it produces tuna that is juicy and full of flavor. In this dish, the wine, butter, and stock gently infuse the tuna as it poaches, and the tuna in turn flavors the incredible sauce that gets spooned over the finished tuna and the herb-scented rice. The tuna cooks perfectly in the hot stock in only five minutes; be careful not to let it overcook. The stock is reduced before the tuna is cooked in order to intensify the flavor, and then reduced again afterward to create a deep, rich sauce without thickeners.
