Ingredients

3/4 cup sugar 

1/4 cup water 

1 1/2 tablespoons light corn syrup 

3 large egg whites, room temperature 

Pinch of salt and cream of tartar 

Preparation

Bring sugar, water, and corn syrup to a boil in a small saucepan, stirring until sugar dissolves. Cook, undisturbed, until syrup registers 248 degrees on a candy thermometer.

Meanwhile, whisk whites with a mixer on low speed until foamy. Add salt and cream of tartar. Increase speed to medium, and whisk until soft peaks form, about 8 minutes.

Reduce speed to low, and pour hot syrup down side of bowl in a slow, steady stream. Increase speed to high, and beat until mixture stops steaming, about 3 minutes. Use immediately.
