Seven-Minute Frosting Recipe

Directions:

1. Mix 1 1/2 cups sugar, the water, and corn syrup in a small saucepan over medium heat. Cook, stirring occasionally, until sugar dissolves. Bring to a boil, and cook until mixture registers 230 degrees on a candy thermometer.
2. Meanwhile, whisk whites with a mixer on medium speed until soft peaks form. With mixer running, add remaining sugar. With mixer on medium-low, pour sugar syrup in a slow, steady stream down side of bowl. Increase speed to medium-high, and whisk until stiff peaks form and mixture is cool, about 7 minutes. Use immediately.
