    Seared Ahi with Grapefruit and Fennel.

    ahiMany of you know how much we like fennel here at the farm. Usually simply caramelized, or in risotto, fennel brings a light anise flavor and subtle, earthy sweetness to many dishes. We love it and think fennel is an underused and under-appreciated ingredient. So when we see a restaurant dish using fennel, we often try it out at home. And in this case, while in Kauai, we tried a dish of seared ahi with a light “slaw” of thinly sliced, barley pickled fennel and supremes of ruby-red grapefruit. It rocked, so we tried to make it at home.

    ahi5ahi6ahi7And we are glad we did. Not only because it was a delicious dish, but it served as a reminder to us about what restaurant dishes we should try to cook at home. In general, we often avoid making restaurant dishes, they tend to be complex, use purposefully esoteric ingredients and are often cooked with equipment most home cooks just don’t have. But then there are restaurant dishes that simply combine quality fresh ingredients with a few basic techniques. The resulting dish seems upscale, and it is, but anyone can make the dish if they know a few tricks. This is one of those dishes.

    ahi4ahi3All you need to make this dish is some very fresh ahi (and that may take some time to find, save this recipe for when you get it), a rocket-hot pan, a very sharp knife and some technique. The hot pan is to sear the seasoned ahi about 45-60 seconds per side (max). That is all you need, then slice the ahi to stop any cooking in residual heat.The sharp knife is to peel the grapefruit and cut “supremes” from between the membranes. This seems like a lot of work, but it takes just a few minutes and is easier than you think. Just do it over a bowl and reserve the juice. Then thinly slice the fennel (we add some radish as well). And if you have a small hand-slicer or mandolin, this gets even easier.

    ahi8ahi9To finish the dish you simply make a quick pickle of the sliced fennel and radish. Quick pickling is one of the easiest ways to quickly add flavor to a dish, you just combine sugar and salt with sliced veggies for about 15 minutes then drain the veggies. We add a splash of rice wine vinegar here as well. Then you assemble the dish. Layer the grapefruit supremes and slices of the ahi and then add a splash of the reserved juice and a bit of rice wine vinegar. Then add the pickled fennel and radish. Season and serve. And the whole thing takes maybe 25-30 minutes.

    ahi1And what do you get? A beautiful, flavorful and balanced dish that is pretty healthy, too. The light but meaty ahi goes very well with the acid of the grapefruit and the sweet, earthy crunch of the fennel and radish. It looks and tastes like a restaurant dish, but almost any home cook can make it.

    Notes before you start:

    • You can use most types of tuna for this dish, and you do not have to serve it as rare as we do. But tuna past medium-rare gets very dry. Tuna is expensive, so if you prefer well-cooked fish, other recipes may be a better choice.

    What You Get: A restaurant-quality dish with less work than you think.

    What You Need: No special equipment required, but a hand-slicer or mandolin is always nice for slicing veggies.

    How Long? 25-30 minutes with 10 minutes of active time. This dish takes less time than you might expect. Anytime dish.
