tablespoons (2 envelopes) unflavored gelatin
cup granulated sugar
teaspoons light corn syrup
teaspoons vanilla extract
Powdered sugar, as needed
Special equipment: 4 bamboo sticks
Line a baking sheet or dish with parchment paper. Stir the gelatin into 1/3 cup water. Place the granulated sugar, 1/3 cup water and corn syrup in a small saucepan over medium-high heat. Bring to a boil, stirring, and cook until the sugar dissolves and the temperature reaches 240 degrees F. Carefully pour the sugar mixture into the gelatin mixture, stirring constantly. Let sit for 5 minutes. Using an electric mixer, whip the egg whites until soft peaks form. With the mixer on medium-low speed, pour the sugar-gelatin mixture into the egg whites in a slow, steady stream. Continue whipping until stiff peaks form. Pour the mixture into 8-by-8-inch baking sheet or dish and refrigerate until stiffened, about 3 hours. Turn the marshmallow out onto a surface sprinkled with powdered sugar; peel off the parchment. Cut into 4 cubes and insert a bamboo stick into each. Serve.
