- Yield: Makes 10 cups
Source: Martha Stewart Living, July 2009
- 1 1/2 cups plus 2 tablespoons sugar
- 2 tablespoons light corn syrup
- 2/3 cup water
- 6 large egg whites, room temperature
- 1 1/2 teaspoons pure vanilla extract
Heat 1 1/2 cups sugar, the corn syrup, and water in a small saucepan over medium heat, stirring constantly, until sugar dissolves. Raise heat to medium-high, and bring to a boil. Wash down sides of pan with a wet pastry brush to prevent sugar crystals from forming. Cook until syrup registers 235 degrees on a candy thermometer. Pour into a glass measuring cup.
Meanwhile, beat whites on medium speed until soft peaks form. Reduce to medium-low, and add remaining 2 tablespoons sugar. Pour syrup into whites in a slow, steady stream down the side of the bowl. Raise speed to medium-high. Beat until stiff peaks form, about 7 minutes. Beat in vanilla. Use immediately.
