You'll hardly recognize your zucchini after transforming it into both a crisp topping and a bed of vegetable noodles. Ingredients:
1 cup plus 2 tablespoons hulled sesame seeds (3 oz) |
4 medium zucchini (2 lb total) |
1 lb well-chilled sushi-grade tuna steaks |
1 tablespoon soy sauce plus additional for serving |
about 4 1/2 cups vegetable oil (about 36 fl oz) |
Directions:
1. Toast sesame seeds: Put oven rack in middle position and preheat oven to 350°F. Toast sesame seeds in a shallow baking pan in oven, stirring occasionally, until golden, 12 to 15 minutes. Cool completely. Transfer 2 tablespoons seeds to a small bowl and 1/4 cup to grinder. Transfer remaining 3/4 cup to a wide shallow bowl.
2. Prepare shoestring zucchini for frying: Halve 3 zucchini crosswise, then cut lengthwise into 3/4-inch shoestrings using slicer. Toss with 1 teaspoon salt in a large sieve set over a bowl and drain 30 minutes.
3. Squeeze handfuls of zucchini to remove moisture, then roll up in a triple layer of paper towels and squeeze to remove remaining moisture.
4. Form burgers: Finely chop tuna with a large wet knife (about 3/4-inch pieces). Stir together soy sauce, 2 tablespoons oil, 1/4 teaspoon salt, and 1/4 teaspoon pepper in a bowl, then stir in tuna. Divide tuna mixture into 4 portions. Pack 1 portion in a 1/2-cup measure, then invert onto seeds in shallow bowl. Gently press tuna to form a patty 3 1/2 inches in diameter, then coat completely with seeds and transfer to a wax-paper-lined plate. Form, coat, and transfer 3 more burgers in same manner. Chill, covered with plastic wrap, until ready to cook. Discard any sesame seeds remaining in shallow bowl.
5. Make sesame mixture: Grind seeds that are already in grinder, pulsing until ground to a flour, then add to remaining seeds (2 tablespoons) in small bowl.
6. Prepare zucchini: Remove julienne attachment from slicer, then cut remaining zucchini lengthwise into 3/4-inch-thick ribbons using slicer. Gently toss with 1/4 teaspoon salt in a large bowl and set aside (zucchini will wilt and become tender).
7. Heat 1 inch oil in a 5- to 6-quart heavy pot over moderate heat until thermometer registers 330°F.
8. Toss all of shoestring zucchini with half of sesame mixture in another large bowl, then fry in 4 batches, turning occasionally with a slotted spoon, until zucchini are golden, about 2 minutes per batch. (Return oil to 330°F between batches.) Transfer zucchini as fried to paper towels to drain. Toss each batch of zucchini immediately with some of remaining sesame mixture.
9. Cook burgers and assemble dish: Heat 3 tablespoons oil in a 12-inch heavy skillet over moderately high heat until hot but not smoking. Cook burgers, turning over once, about 2 minutes total for medium-rare tuna (seeds should be golden brown).
10. Drain zucchini ribbons and divide among 4 plates, then top with burgers and fried shoestring zucchini. Serve burgers with additional soy sauce on the side.
