Step 1

In a bowl, whisk the fish sauce, sugar and crushed garlic. Add the wings and toss to coat. Refrigerate for 3 hours, tossing the wings occasionally.

Step 2

Heat the 2 tablespoons of oil in a small skillet. Add the minced garlic; cook over moderate heat until golden, 3 minutes. Drain on paper towels.

Step 3

In a large pot, heat 2 inches of oil to 350°F (176°C). Pat the wings dry on paper towels; reserve the marinade. Put the cornstarch in a shallow bowl, add the wings and turn to coat. Fry the wings in batches until golden and cooked through, about 10 minutes. Drain on paper towels and transfer to a bowl.

Step 4

In a small saucepan, simmer the marinade over moderately high heat until syrupy, 5 minutes. Strain over the wings and toss. Top with the cilantro, mint and fried garlic and serve immediately.
