Equipment

  • candy thermometer

Ingredients

  • cup water
  • ¾ cup granulated sugar
  • ¾ cup light corn syrup (dark corn syrup or honey can be substituted for a slightly different flavor profile)
  • 3 large egg whites at room temperature
  • ½ tsp cream of tartar
  • 1 tsp vanilla extract (or vanilla bean paste)

Instructions

  • In a medium-sized saucepan combine ⅓ cup water, ¾ cup sugar and ¾ cup corn syrup. Insert a candy thermometer into the mixture and heat over a medium-high flame. Do not stir the sugar water as it cooks, and cook until the mixture reaches 240°F. While waiting, continue onto the next step.
  • While the sugar syrup is cooking, place the egg whites and cream of tartar in the bowl of your stand mixer. Beat the whites to soft peaks. This typically takes 3-4 minutes.
  • When the sugar syrup reaches 240°F, remove immediately from the heat. With the mixer running on medium speed, carefully pour the syrup in a thin stream into the egg whites, whipping the whole time.
  • Continue to whip the mixture for 7-8 minutes or until very thick and glossy. The heat of the sugar mixture will deflate the whites initially, but they will eventually thicken and fluff up.
  • Add 1 tsp vanilla and whip until incorporated.
  • Transfer the fluff into an airtight container like a mason jar. Store for up to 2 weeks at room temperature. The spread can be re-whipped by hand if it starts to separate.
