Tuna Hallalujah

 OMG!!!  Absolutely love this dish.  Of course I am a big fan of Tuna anyway,  but this really is amazing.  It's Horseradish-Crusted Ahi Tuna with Miso Aioli.  This recipe is from The TERRAPIN restaurant in Rhinebeck, New York.  Serves 4.  
White Miso Aoili:

1Cup Mayo, 1/4 C white miso, 1 Tb rice vinegar, 1 large garlic clove, minced, 1 1/2 tsp hot chili sauce (such as sambal oelek or srirachai) Whisk these ingredients in mediumbowl to blend.

Then Mix 1 Cup grated fresh peeled horseradish, 1/2 Cup prepared horseradish and 1/2 cup panko breadcrumbs in medium bowl.  Divide mixture among  4 1" thick tuna steaks- (about 1 1/2 lbs), pat evenly over top of each steak, crust should be about 1/4" thick.  Heat 2 Tb sesame oil on nonstick skillet over high heat.  Add tuna steaks, crust side  down.  Cook until crust is browned, about 3 minutes.  Using spatula, turn steaks over and cook until lightly browned, about 1 minute. Serve tuna with miso aioli.  
We grilled this on cast iron, it was fun, quick and we were so impressed with the flavor. It was such a wonderful surprise.
