• 1/2 teaspoon salt, divided

Cooking Directions

Step 1

Place shallot, bay leaf and wine in a small saucepan and bring to a boil. Reduce until the wine is almost evaporated, about 5 minutes. Remove from the heat, discard bay leaf and transfer to a small bowl. Add sour cream, lemon juice, 1 teaspoon dill, mustard and 1/4 teaspoon salt; stir to combine.

Step 2

Put breadcrumbs, pistachios, the remaining 1 teaspoon dill and 1/4 teaspoon salt in a blender or food processor. Process until finely ground. Transfer to a shallow bowl. Dredge both sides of the tuna in the pistachio mixture.

Step 3

Heat oil in a large nonstick skillet over medium heat. Add the tuna and cook until browned, adjusting the heat as necessary to prevent burning, 4 to 5 minutes per side for medium-rare. Serve with the lemon-dill sauce.
