Blood Orange Vinaigrette:
- 1 Blood Orange, 1 tsp. zest removed, supremed*, juice reserved
- 1 Red Ruby Grapefruit, supremed*, juice reserved
- 2 tbsp. red wine vinegar
- 1 tbsp. honey
- 1 tbsp. soy sauce
- ½ tsp. Dijon mustard
- ½ c. extra-virgin olive oil
- kosher salt and freshly ground black pepper
- 4 Wild Sashimi Tuna steaks, approx. 7 oz. each and 1 inch thick
- 5 oz. mixed baby greens
- 1 ripe Hass avocado, peeled, pitted, and diced
- 2 tablespoons minced shallot
- Kosher salt and freshly ground black pepper
- ¼ c. coarsely chopped unsalted peanuts or cashews
For the orange, finely grate 1 tsp. zest. Cut off the peel and pith and cut the flesh into supremes*, reserving the juice. For the grapefruit, cut off the peel and pith and cut the flesh into supremes, reserving the juice. You should have about 1/3 c. mixed citrus juice. (See Note.)
To make the vinaigrette: Add citrus juice to small sauce pan over high heat. Bring to a boil and reduce until roughly 2 tbsp. remain, about 3-5 minutes. This can also be done by heating in a microwave on high about 5 minutes.**
In a medium bowl, whisk together reduced citrus juice, reserved orange zest, vinegar, honey, soy sauce and mustard. Add the oil in a slow stream while whisking constantly. Season to taste with salt and pepper. Reserve half (about 1/3 c.) of the vinaigrette for dressing the salad.
Pour remaining half of vinaigrette into a 1-gal. plastic bag. Add tuna and refrigerate for 30 minutes to 1 hour, no longer.
Heat a large nonstick skillet over medium-high heat. Remove the tuna and discard marinade. Add tuna, searing on one side, about 1-2 minute. Turn and sear the other side, about 1-2 minute more, for rare to medium-rare tuna. Transfer to a carving board.
In a large bowl, gently toss the greens with the reserved vinaigrette. Add the citrus supremes, avocado and shallot and toss again. Season to taste with salt and pepper. Divide among four dinner plates. Slice each tuna steak across the grain into 1/2-inch slices. Top each salad with a tuna steak, fanning out the slices. Sprinkle with the peanuts and serve.
