Ingredients

  • 3 large egg whites
  • ½ teaspoon cream of tartar
  • ¾ cup light corn syrup
  • ⅓ cup water
  • ⅔ cup granulated sugar divided
  • ½ teaspoon vanilla extract

Instructions

    Cup of Yum
  1. Fit a stand mixer with a whisk attachment. Add the egg whites and cream of tartar and beat on medium speed until foamy.
  2. Add 2 tablespoons of sugar and beat until soft peaks form, set aside.
  3. Meanwhile, in a medium saucepan, combine water, corn syrup, and the remaining sugar.
  4. Cook over medium-high heat while stirring until the mixture reaches firm ball stage (*see notes) or 248°F on a candy thermometer. This step will take about 10-12 minutes.
  5. Once the corn syrup mixture reaches firm ball stage, turn the mixer on to medium and in a slow steady stream, pour the sugar syrup mixture into the beaten egg whites in the mixer bowl.
  6. Once all of the corn syrup mixture has been added, beat on high for 5 minutes.
  7. Add vanilla extract and beat on high for 1 minute.
  8. Store in a tightly sealed container.
