　　Egg whites give these quick, cheesy nibbles their exceptionally light texture. Bite-size portions make them the perfect mouth-popping accompaniment to an aperitif.

　　

Ingredients

Makes about 32 hors d'oeuvres

　　About 6 cups vegetable oil

　　1/4 pound finely grated Parmigiano-Reggiano (2 cups)

　　1/4 cup all-purpose flour

　　1/2 teaspoon black pepper

　　1/4 teaspoon salt

　　4 large egg whites at room temperature

　　

Special Equipment

a deep-fat thermometer

　　

Step 1

Heat 2 inches oil in a deep 3-quart heavy saucepan over moderate heat until it registers 360°F on thermometer.

　　

Step 2

While oil heats, mix together cheese, flour, pepper, and salt in a bowl until combined well. Beat whites in another bowl with an electric mixer until they just hold stiff peaks. Fold in 1/2 cup cheese mixture to lighten, then fold in remaining cheese mixture gently but thoroughly.

　　

Step 3

Drop about 8 teaspoons of batter, 1 teaspoon at a time, into oil and fry, turning occasionally, until balls of batter are puffed, crisp, and golden, about 2 minutes. Transfer with a slotted spoon to paper towels to drain briefly. Make 3 more batches in same manner, returning oil to 360°F between batches. Serve immediately.
