9 cups


  • 4 teaspoons unflavored gelatin (from 2 envelopes)

  • 1/4 cup plus 2 tablespoons water

  • 2 cups sugar

  • 3/4 cup light corn syrup

  • 6 large egg whites

  • 1/4 teaspoon fresh lemon juice

  • 1/8 teaspoon salt


  1. In a small microwavable bowl, sprinkle the gelatin over 3 tablespoons of the water and let stand until softened.

  2. In a medium saucepan, combine 1 1/2 cups of the sugar with the corn syrup and the remaining 3 tablespoons of water. Bring to a boil, stirring, until the sugar is dissolved. Keep warm.

  3. Meanwhile, in a standing electric mixer fitted with a whisk, beat the egg whites with the lemon juice and salt until soft peaks form. Gradually add the remaining 1/2 cup of sugar, beating at high speed until stiff and glossy. With the mixer at medium speed, slowly and carefully add the hot sugar syrup in a thin stream. When all of the syrup has been added, beat the meringue at medium-high speed until slightly cooled, about 5 minutes. Microwave the gelatin until melted, about 15 seconds. With the mixer on, beat the melted gelatin into the meringue. Use right away.
