Ingredients

1/4 cup rice-wine vinegar

1 teaspoon sugar

1 tablespoon freshly squeezed lemon juice

2 tablespoons soy sauce

1/4 teaspoon freshly ground black pepper

1/2 cup Homemade Mayonnaise, or prepared

12 ounces sushi-quality tuna

4 small navel or juice oranges, cut into 1/4-inch-thick slices

3 tablespoons nonpareil capers, drained

1/2 bunch fresh cilantro, leaves only

Preparation

In a small bowl, combine the vinegar, sugar, lemon juice, soy sauce, and black pepper to make a ponzu sauce. In a separate bowl, combine 1 tablespoon soy-sauce mixture with mayonnaise; set aside.

Remove tuna from freezer; slice into thirty-six 1/8-by-1 1/2-by-2 1/4-inch rectangles. Arrange slice of tuna on top of an orange slice. Drizzle with 1/4 teaspoon of mayonnaise mixture; garnish with several capers and cilantro. Repeat with remaining ingredients. Serve immediately.
