Equipment

  • candy thermometer

Ingredients
  

  • 3 egg whites
  • ½ teaspoon cream of tartar
  • ¾ cup corn syrup
  • ¾ cup granulated sugar
  • 1 teaspoon vanilla extract
  • ⅓ cup water

Instructions
 

  • Mix egg whites and cream of tartar in a medium mixing bowl until foamed over. Set aside.
  • In a medium saucepan, add water, sugar, and corn starch and cook over medium-low heat. Stir to dissolve sugar and then don't stir again. Heat mixture to 240°F or soft ball on a candy thermometer. Remove from heat.
  • Mix the foamed egg whites again, this time on medium until they form soft peaks.
  • Change the speed to high and slowly drizzle the hot syrup in.

Notes

Make sure to use a candy thermometer for measuring the temperature correctly.
